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.

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.

The enable logic control function puts the device

into shutdown mode allowing a total current

consumption low

er than 1 μA.

The device also includes short-circuit and thermal

protection.

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.

Several small package options are available.
