Pin Functions

PIN I/O DESCRIPTION
NAME NO.
EN 3 I Enable pin. Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts the regulator into shutdown mode.
For TLV742P, output voltage is discharged through an internal 120-Ω resistor when device is shut down.
GND 2 — Ground pin
IN 4 I Input pin. For good transient performance, place a small 1-µF ceramic capacitor from this pin to ground. See Input and Output Capacitor Requirements for more details.
OUT 1 O Regulated output voltage pin. A small 1-μF ceramic capacitor is required from this pin to ground to ensure stability. See Input and Output Capacitor Requirements for more details.
Thermal pad — — The thermal pad is electrically connected to the GND node. Connect to the GND plane for improved thermal performance.
