DIA7965

Version 1.0, Dec 2023

Automotive 500 mA, High PSRR Low I_QLDO

 Features

 Description



AEC-Q100 qualified:

The DIA7965 series is a 500 mA, ultra-high Power

Supply Ripple Rejection (PSRR) low dropout CMOS

linear regulator. The device features ultra-high PSRR

and low noise to meet the requirements of RF and

other sensitive analog circuits in automotive

applications.

−

Device ambient temperature:

-40 °C ≤ T_A≤ 125 °C

Device junction temperature:

-40 °C ≤ T_J≤ 150 °C



Operating input voltage range: 1.65 V to 5.5 V

Available in various fixed voltage options:

1 V to 3.3 V

The DIA7965 operates an input voltage range of 1.65

V to 5.5 V and supports fixed output voltage from 1 V

to 3.3 V. With 18 µA low quiescent current at no load,

the DIA7965 is quite suitable for systems requiring

low power and provides fast line and load transient

performance.



Ultra-high PSRR and low noise:

−

PSRR: 95 dB (typ.) at f = 1 kHz

Noise: 20 µV_RMS

Low quiescent current：

−

18 µA typical at no load

10 nA shutdown current

The DIA7965 is stable with an 1 µF input and an 1 µF

output small ceramic capacitor, allowing for a small

overall solution size. A precision band-gap and error

amplifier provide high accuracy of ±2% over

operating temperature range. The DIA7965 is

available in SOT23-5 and tiny DFN1*1-4 packages.
