LD57100 Datasheet 1a Ultra Low-dropout Ldo

Manufacturer: STMicroelectronics

Overview: LD57100 Datasheet 1 A ultra low-dropout LDO with bias Product status link.

General Description

The LD57100 is a high accuracy voltage regulator, which provides 1 A of current.

It is equipped with an NMOS pass transistor, whose gate is biased by a dedicated pin, thus allowing the ultra-low drop performance even at very low input voltages.

It is available in Flip Chip6 (0.8x1.2 mm), maximizing the space saving.

Key Features

  • Input voltage from VOUT to 5.5 V.
  • Input bias supply pin from 3.0 V to 5.5 V.
  • Ultra low-dropout voltage (40 mV typ. at 1 A load).
  • Low ground current (35 μA typ. at no load).
  • Output voltage tolerance: ±1% all over temperature range, ±0.5% at 25 °C.
  • 1 A guaranteed output current.
  • 50 mV output voltage step available from 0.4 V to 1.8 V.
  • 100 mV output voltage step available from 1.9 V to 3.6 V.
  • Adjustable version from 0.
