LP5907
SNVS798O –APRIL 2012–REVISED JUNE 2020
LP5907 250-mA, Ultra-Low-Noise, Low-IQ LDO
1 Features
3 Description
The LP5907 is a low-noise LDO that can supply up to
1
•
•
•
Input voltage range: 2.2 V to 5.5 V
Output voltage range: 1.2 V to 4.5 V
250 mA output current. Designed to meet the
requirements of RF and analog circuits, the LP5907
device provides low noise, high PSRR, low quiescent
current, and low line or load transient response
figures. Using new innovative design techniques, the
LP5907 offers class-leading noise performance
without a noise bypass capacitor and the ability for
remote output capacitor placement.
Stable with 1-µF ceramic input and output
capacitors

No noise bypass capacitor required
Remote output capacitor placement
Thermal-overload and short-circuit protection
–40°C to 125°C operating junction temperature
Low output voltage noise: < 6.5 µVRMS
PSRR: 82 dB at 1 kHz
The device is designed to work with a 1-µF input and
a 1-µF output ceramic capacitor (no separate noise
bypass capacitor is required).
Output voltage tolerance: ±2%
This device is available with fixed output voltages
from 1.2 V to 4.5 V in 25-mV steps. Contact Texas
Instruments Sales for specific voltage option needs.
Very low IQ (enabled): 12 µA
Low dropout: 120 mV (typical)
