The LP5912-EP is a low-noise, low-dropout regulator (LDO) that can supply up to 500 mA of output current. Designed to meet the requirements of RF and analog circuits, the LP5912-EP provides low noise, high PSRR, low quiescent current, and low line and load transient response. The LP5912-EP offers class-leading noise performance without a noise bypass capacitor and with the ability for remote output capacitance placement.
The device is designed to work with a 1-µF input and a 1-µF output ceramic capacitor (a separate noise bypass capacitor is not required).
This device is available with fixed output voltages from 0.8 V to 5.5 V in 25-mV steps. Contact the Texas Instruments Sales office for specific voltage option requirements.

1 | OUT | O | Regulated output voltage. |
2 | NC | — | No internal connection. Leave open, or connect to ground. |
3 | PG | O | Power-good indicator. Requires an external pullup resistor. |
4 | EN | I | Enable input. Logic high = device is on, logic low = device is off, with an internal 3-MΩ pulldown resistor. |
5 | GND | G | Ground. |
6 | IN | I | Unregulated input voltage. |
Thermal pad | — | Connect this pad to the copper area under the package to improve thermal performance. Use thermal vias to transfer heat to inner layers of the printed circuit board (PCB). Connect the thermal pad to ground, or leave floating. Do not connect the thermal pad to any potential other than ground. |
