Product Information

Features

  • Available in 2.5-V, 3-V, 3.3-V, 4.85-V, and 5-V Fixed-Output and Adjustable Versions
  • Integrated Precision Supply-Voltage Supervisor Monitoring Regulator Output Voltage
  • Active-Low Reset Signal with 200-ms Pulse Width
  • Very Low Dropout Voltage...Maximum of 35 mV at IO = 100 mA (TPS7350)
  • Low Quiescent Current - Independent of Load...340 uA Typ
  • Extremely Low Sleep-State Current, 0.5 uA Max
  • 2% Tolerance Over Full Range of Load, Line, and Temperature for Fixed-Output Versions§
  • Output Current Range of 0 mA to 500 mA
  • TSSOP Package Option Offers Reduced Component Height For Critical Applications

§ The TPS7325 has a tolerance of ±3% over the full temperature range.
The TPS71xx and the TPS72xx are 500-mA and 250-mA output regulators respectively, offering performance similar to that of the TPS73xx but without the delayed-reset function. The TPS72xx devices are further differentiated by availability in 8-pin thin-shrink small-outline packages (TSSOP) for applications requiring minimum package size.

Description

The TPS73xx devices are members of a family of micropower low-dropout (LDO) voltage regulators. They are differentiated from the TPS71xx and TPS72xx LDOs by their integrated delayed microprocessor-reset function. If the precision delayed reset is not required, the TPS71xx and TPS72xx should be considered.

The RESET\ output of the TPS73xx initiates a reset in microcomputer and microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS73xx monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage.

If that occurs, the RESET\ output (open-drain NMOS) turns on, taking the RESET\ signal low. RESET\ stays low for the duration of the undervoltage condition.
