The series achieves high ripple rejection and low dropout and consists of a standard voltage source, an error correction, current limiter and a phase compensation circuit plus a driver transistor. Output voltage is selectable in 50mV increments within a range of 1.8V ~ 6.0V. The series is also compatible with low ESR ceramic capacitors which give added output stability. This stability can be maintained even during load fluctuations due to the excellent transient response of the series. The current limiter's foldback circuit also operates as a short protect for the output current limiter and the output pin. The CE function enables the output to be turned off, resulting in greatly reduced power consumption.

The P-Channel MOSFET, which is connected to the VOUT pin, is then driven by the subsequent output signal. The ouput voltage at the VOUT pin is controlled & stabilised by a system of negative feedback. The current limit circuit and short protect circuit operate in relation to the level of output current. Further, the IC's internal circuitry can be shutdown via the CE pin's signal. each circuit Current Limit VOUT R2 R1 Voltage Reference VSS Low ESR Capacitors With the XC6204 series, a stable output voltage is achievable even if used with low ESR capacitors as a phase compensation circuit is built-in. In order to ensure the effectiveness of the phase compensation, we suggest that an output capacitor (CL) is connected as close as possible to the output pin (VOUT) and the VSS pin. Please use an output capacitor with a capacitance value of at least 1F. Also, please connect an input capacitor (CIN) of 0.1F between the VIN pin and the VSS pin in order to ensure a stable power input.

When the load current reaches the current limit level, the fixed current limiter circuit operates and output voltage drops. As a result of this drop in output voltage, the foldback circuit operates, output voltage drops further and output current decreases (refer to the data on page 5). When the output pin is shorted, a current of about 60mA flows. CE Pin The IC's internal circuitry can be shutdown via the signal from the CE pin with the XC6204 series. In shutdown mode, output at the VOUT pin will be pulled down to the VSS level via R1 & R2. The operational logic of the IC's CE pin is selectable (please refer to the selection guide on page 2). Note that as the standard XC6204B type is ' High Active/No Pull Down' , operations will become unstable with the CE pin open. Although the CE pin is equal to an inverter input with CMOS hysteresis, with either the pull-up or pull-down options, the CE pin input current will increase when the IC is in operation. We suggest that you use this IC with either a VIN voltage or a VSS voltage input at the CE pin. If this IC is used with the correct specifications for the CE pin, the IC will operatenormally. However, supply current may increase as a result of through current in the IC's internal circuitry if a voltage between 0.25V and 1.5V is input. " Notes on Use 1. Please use this IC within the stated absolute maximum ratings. The IC is liable to malfunction should the ratings be exceeded. 2. Where wiring impedence is high, operations may become unstable due to noise and/or phase lag depending on output current. Please strengthen VIN and VSS wiring in particular. 3. Please wire the input capacitor (CIN) and the output capacitor (CL) as close to the IC as possible. 6 XC6204 Series "XC6204 (1)Output Voltage vs. Output Current XC6204x182 2.5 Output Voltage VOUT(V) 2.0 1.5 1.0 0.5 0.0 0 50 100 150 200 250 300 350 Output Current IOUT(mA) ------------ 85OC O 25 C -40 C O High Speed LDO Regulators XC6204x182 2.5 Output Voltage VOUT(V) 2.0 1.5 1.0 0.5 0.0 0 50 100 150 200 250 300 350 Output Current IOUT(mA) VIN=2.1V VIN=2.8V VIN=5.0V VIN=10V Topr=25OC CIN=CL=1.0uF(ceramic) VIN=2.8V CIN=CL=1.0uF(ceramic) XC6204x252 3.0 Output Voltage VOUT(V) 2.5 2.0 1.5 1.0 0.5 0.0 0 50 100 150 200 250 300 350 Output Current IOUT(mA) ------------ 85OC O 25 C -40 C O XC6204x252 3.0 Output Voltage VOUT(V) 2.5 2.0 1.5 1.0 0.5 0.0 0 50 100 150 200 250 300 350 Output Current IOUT(mA) VIN=2.8V VIN=3.5V VIN=5.0V VIN=10V Topr=25OC CIN=CL=1.0uF(ceramic) VIN=3.5V CIN=CL=1.0uF(ceramic) XC6204x302 4.0 Output Voltage VOUT(V) VIN=4.0V CIN=CL=1.0uF(ceramic) XC6204x302 4.0 Output Voltage VOUT(V) Topr=25OC CIN=CL=1.0uF(ceramic) 3.0 ------------ 85 C O 25 C -40 C O O 3.0 VIN=3.3V VIN=4.0V 2.0 2.0 VIN=7.0V VIN=10V 1.0 1.0 0.0 0 50 100 150 200 250 300 350 Output Current IOUT(mA) 0.0 0 50 100 150 200 250 300 350 Output Current IOUT(mA) 7 XC6204 Series High Speed LDO Regulators (1)Output Voltage vs. Output Current (Contd.)
