General Description

The TC1303/TC1304 combines a 500 mA synchronous buck regulator and 300 mA Low-Dropout Regulator (LDO) with a power-good monitor to provide a highly integrated solution for devices that require multiple supply voltages.

The unique combination of an integrated buck switching regulator and low-dropout linear regulator provides the lowest system cost for dual-output voltage applications that require one lower processor core voltage and one higher bias voltage.

The 500 mA synchronous buck regulator switches at a fixed frequency of 2.0 MHz when the load is heavy, providing a low noise, small-size solution.

Overview

TC1303A/TC1303B/ TC1303C/TC1304 500 mA Synchronous Buck Regulator, + 300 mA LDO with Power-Good.

Key Features

  • Dual-Output Regulator (500 mA Buck Regulator and 300 mA Low-Dropout Regulator).
  • Power-Good Output with 300 ms Delay www. DataSheet4U. com.
  • Total Device Quiescent Current = 65 µA, Typ.
  • Independent Shutdown for Buck and LDO Outputs (TC1303).
  • Both Outputs Internally Compensated.
  • Synchronous Buck Regulator: - Over 90% Typical Efficiency - 2.0 MHz Fixed-Frequency PWM (Heavy Load) - Low Output Noise - Automatic PWM to PFM mode transition - Adjustab.
