Design LP5912
SNVSA77D – DECEMBER 2015 – REVISED NOVEMBER 2016 LP5912 500-mA Low-Noise, Low-IQ LDO
1 Features 3 Description The LP5912 is low-noise LDO that can supply up to
500 mA of output current. Designed to meet the
requirements of RF and analog circuits, the LP5912
device provides low noise, high PSRR, low quiescent
current, and low line and load transient response.
The LP5912 offers class-leading noise performance
without a noise bypass capacitor and with the ability
for remote output capacitance placement. 1 Input Voltage Range: 1.6 V to 6.5 V
Output Voltage Range: 0.8 V to 5.5 V
Output Current up to 500 mA
Low Output-Voltage Noise: 12 ВµVRMS Typical
PSRR at 1 kHz: 75 dB Typical
Output Voltage Tolerance (VOUT ≥ 3.3 V): ±2%
Low IQ (Enabled, No Load): 30 ВµA Typical
Low Dropout (VOUT ≥ 3.3 V): 95 mV Typical at …
