SC1531 - 200mA & 250mA SmartLDOs

General Description

The SC1531(A) is designed to maintain a glitch-free 3.3V output when at least one of two inputs, 5V (VIN) and 3.3V (VAUX), is present.

Key Features

  • Glitch-free transition between input sources Internal logic selects input source Gate drive for external PMOS bypass switch 5V detection with hysteresis 1% regulated output voltage accuracy 200mA load current capability (250mA for SC1531A) Remote sense SO-8 package u u u u Whenever VIN exceeds a predetermined threshold value, u the internal 3.3V linear regulator is enabled, and DR is u pulled high. u When VIN falls below a lower threshold value, DR is pulled u low and the internal linear regula.
