DIO7961

450 mA, Ultra-Low Noise and High PSRR LDO for Radio

Frequency and Analog Circuits

Features

Descriptions



Operating input voltage range: 1.65 V to 5.5 V

The DIO7961 series is a 450 mA, ultra-high PSRR,

ultra-low noise, high-accuracy, and low dropout

CMOS linear regulator with high ripple rejection.

The device is ideal for radio frequency and analog

circuits for its low quiescent current consumption

and fast line and load transient performance. The

DIO7961 operates over an input voltage range of

1.65 V to 5.5 V and supports fixed output voltage

from 1 V to 3.3 V.

Available in fixed voltage option: 1 V to 3.3 V

Output current：450 mA

Ultra high PSRR: Typ. 95 dB at f = 1 kHz

Ultra low noise: 10 µV_RMS

Output voltage accuracy: ±1%

Ultra-low quiescent current : Typ. 18 µA

Standby current: Typ. 0.1 µA

Very low dropout: 180 mV at 450 mA

Stable with a 1 µF small case size ceramic

capacitor

The DIO7961 is designed to work with a 1 µF input

and a 1 µF output ceramic capacitor, allowing for

a small overall solution size. A precision band-gap

and error amplifier provide high accuracy of ±1%

(max) at 25°C. It is available in SOT23-5, WLCSP-4

(0.65 mm*0.65 mm*0.33 mm, pitch 0.35 mm) and

DFN1*1-4 packages.
