FUNCTION
Shutdown—active low. Ground to power-down chip, tie to V+ for normal operation.
Output voltage falls to 0V when SHDN is low.
Reference-Voltage Output (+1.23V) supplies up to 100μA for extended loads.
Bypass to GND with a capacitor that does not exceed 0.047μF.
Soft-Start. Capacitor between SS and GND provides soft-start and short-circuit protection.
510k ? resistor from SS to SHDN provides current boost.
Compensation Capacitor Input externally compensates the outer feedback loop.
Connect to OUT with a 330pF capacitor.
Output Voltage Sense Input provides regulation feedback sensing. Connect to +5V output.
Ground pins are internally connected. Connect both pins to ground.
Drain of internal P-channel power MOSFET.
Supply-Voltage Input. Bypass to GND with 1μF ceramic and large-value electrolytic capaci-
tors in parallel. The 1μF capacitor must be as close to V+ and GND pins as possible.
No Connect—no internal connections to these pins.
