LMR10510 - Step-Down Voltage Regulator

General Description

The LMR10510 regulator is a monolithic, high frequency, PWM step-down DC/DC converter in a 5pin SOT-23 and a 6-pin WSON package.

It provides all the active functions to provide local DC/DC conversion with fast transient response and accurate regulation in the smallest possible PCB area.

Key Features

  • 1 Input Voltage Range of 3 V to 5.5 V.
  • Output Voltage Range of 0.6 V to 4.5 V.
  • Output Current up to 1 A.
  • 1.6-MHz (LMR10510X) and 3-MHz (LMR10510Y) Switching Frequencies.
  • Low Shutdown IQ, 30 nA Typical.
  • Internal Soft Start.
  • Internally Compensated.
  • Current-Mode PWM Operation.
  • Thermal Shutdown.
  • SOT-23 (2.92 × 2.84 × 1 mm) and WSON (3 × 3 × 0.8 mm) Packaging.
  • Tiny Overall Solution Reduces System Cost.
