CAT6219 500 mA CMOS LDO Regulator
Description
The CAT6219 is a 500 mA CMOS low dropout regulator that provides fast response time during load current and line voltage changes. The quick-start feature allows the use of an external bypass capacitor to reduce the overall output noise without affecting the turn-on time of just 150 ms. With zero shutdown current and low ground current of 55 mA typical, the CAT6219 is ideal for battery-operated devices with supply voltages from 2.3 V to 5.5 V. An internal under voltage lockout circuit disables the output at supply voltages under 2.15 V typical. The CAT6219 offers 1% initial accuracy and low dropout voltage, 300 mV typical at 500 mA. Stable operation is provided with a small value ceramic capacitor, reducing required board space and component cost. Other features include current limit and thermal protection. The LDO is available in fixed and adjustable output in the low profile (1 mm max height) 5-lead TSOT23 and in the 6-pad 2 mm x 2 mm TDFN packages.

Figure 2. Adjustable Output LDO
EN is the enable control logic (active high) for the regulator output. It has a 2.5 MW pull-down resistor, which assures that if EN pin is left open, the circuit is disabled. VOUT is the LDO regulator output. A small 2.2 mF ceramic bypass capacitor is required between the VOUT pin and ground. For better transient response, its value can be increased to 4.7 mF. The capacitor should be located near the device. For the SOT23-5 package, a continuous 500 mA output current may turn-on the thermal protection. A 250 W internal shutdown switch discharges the output capacitor in the no-load condition. GND is the ground reference for the LDO. The pin must be connected to the ground plane on the PCB. BYP is the reference bypass pin. An optional 0.01 mF capacitor can be connected between BYP pin and GND to reduce the output noise and enhance the PSRR at high frequency. ADJ is the adjustable input pin for the adjustable LDO. The pin is connected to the resistor voltage divider.

Pin Function VIN is the supply pin for the LDO. A small 1 mF ceramic bypass capacitor is required between the VIN pin and ground near the device. When using longer connections to the power supply, CIN value can be increased without limit. The operating input voltage range is from 2.3 V to 5.5 V.
Table 2. ABSOLUTE MAXIMUM RATINGS
Parameter VIN VEN, VOUT Junction Temperature, TJ Power Dissipation, PD Storage Temperature Range, TS Lead Temperature (soldering, 5 sec.) ESD Rating (Human Body Model)
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.

NOTE: Typical application circuit with external components is shown above. 1. The maximum allowable power dissipation at any TA (ambient temperature) is PDmax = (TJmax - TA)/qJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. 2. The device is not guaranteed to work outside its operating rating.
