Pin Functions

PIN I/O DESCRIPTION
NAME NO.
PG 5 Output Power-good output
EN 4 Input Enable pin. Drive EN greater than VEN(HI) to turn on the regulator.
Drive EN less than VEN(LO) to put the LDO into shutdown mode.
FB 2 — This pin is used as an input to the control loop error amplifier and is used to set the output voltage of the LDO.
GND 3 — Ground pin
IN 6 Input Input pin. For best transient response and to minimize input impedance, use the recommended value or larger ceramic capacitor from IN to ground as listed in the Recommended Operating Conditions table and the Input and Output Capacitor Selection section. Place the input capacitor as close to the output of the device as possible.
OUT 1 Output Regulated output voltage pin. A capacitor is required from OUT to ground for stability. For best transient response, use the nominal recommended value or larger ceramic capacitor from OUT to ground; see the Recommended Operating Conditions table and the Input and Output Capacitor Selection section. Place the output capacitor as close to output of the device as possible.
Thermal pad Pad — Connect the thermal pad to a large area GND plane for improved thermal performance.
