The output voltage is fed back through an internal resistor voltage divider connected to the VOUT pin. The reference is connected to the error amplifier's inverting input. The error amplifier compares the reference with the feedback voltage and amplifies the difference. If the feedback voltage is lower than the reference voltage, the pass transistor's gate is pulled lower, which allows more current to pass to the output and increase the output voltage. On the other hand, if the feedback voltage is too high the pass transistor gate is pulled up, allowing less current to pass to the output, resulting a decrease in output voltage. The current-limiter monitors and controls the pass-transistor's gate voltage, limiting the output current to its specified maximum value. Thus it can withstand a short-circuited output for an indefinite amount of time without damaging the part. SA57004-XX VIN 5 4 VOUT R VREF R 10 k ON/OFF 1 CURRENT LIMIT R 2 GND SL01442 Figure 17.

Typical application circuit. The following points must be considered for good performance from these devices: Input capacitor: An input capacitor of 1 F is required between the SA57004-XX input and the ground (the amount of capacitance may be increased without limit). This capacitor must be located as close as possible to VIN or GND pin (not more than 1 cm) and returned to a clean analog ground. Any good quality ceramic, tantalum or film capacitor will work. Output capacitor: Phase compensation is made for securing stable operation even if the load current varies. For this reason, an output capacitor with good frequency characteristics is needed. Set it as close to the circuit as possible and make the wiring as short as possible. The value of the output capacitance must be at least 1 F. Also it must have the ESR (Equivalent Series Resistance) value within the stable range shown in Figure 12, `ESR stable region'. ON/OFF (Chip Enable) pin: The ON/OFF pin must be actively terminated. If the function is not to be used, the pin should be tied to VIN. Line impedance of VDD and GND: The VIN and GND lines should be sufficiently wide. Otherwise, when the impedance of these lines is high, there is a chance to pick up noise or malfunction. 2001 Dec 17 8 Philips Semiconductors Product data Low-noise 150 mA linear CMOS regulator SA57004-XX PACKING METHOD The SA57004-XX is packed in reels, as shown in Figure 19.
