LDLN025

250 mA ultra low noise LDO

Datasheet - production data

Description

The LDLN025 is a 250 mA low-dropout voltage

regulator, able to work with an input voltage

range from 1.5 V to 5.5 V.

The typical dropout voltage at 250 mA load is

120 mV.

The very low quiescent current, which is just

12 μA at no-load, extends battery-life of

applications requiring very long standby time.

Features

Thanks to its ultra low noise value and high

PSRR, the LDLN025 provides a very clean

output, suitable for ultra-sensitive loads. It is

stable with ceramic capacitors.



Ultra low output noise: 6.5 μV_RMS

Operating input voltage range: 1.5 V to 5.5 V

Output current up to 250 mA

Very low quiescent current: 12 μA at no-load

Controlled I_qin dropout condition

Very low-dropout voltage: 250 mV at

250 mA

The enable logic control function puts the device

into shutdown mode allowing a total current

consumption lower than 1 μA.

The device also includes short-circuit and thermal

protection.



Very high PSRR: 80 dB@100 Hz,

60 dB@100 kHz

Output voltage accuracy: 2% across line,

load and temperature

Output voltage versions: from 1 V to 5 V,

with 50 mV step

Typical applications are noise sensitive loads

such as ADC, VCO in mobile phones and tablets,

wireless LAN devices. The LDLN025 is designed

to keep the quiescent current under control and

at a low value also during dropout operation,

extending the operating time of battery-powered

devices.



Logic-controlled electronic shutdown

Output discharge feature

Internal soft-start

Overcurrent and thermal protections

Temperature range: from -40 °C to +125 °C

Packages: Flip-Chip4, DFN4-1x1

Several small package options are available.

Applications



Smartphones/tablets

Image sensors

Instrumentation

VCO and RF modules
