General Description

The TPS775xx devices are designed to have a fast transient response and be stable with a 10-μF low ESR capacitors.

This combination provides high performance at a reasonable cost.

Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 169 mV at an output current of 500 mA for the TPS77533) and is directly proportional to the output current.

Overview

TPS77501-EP, TPS77515-EP, TPS77516-EP, TPS77518-EP TPS77525-EP, TPS77533-EP WITH RESET OUTPUT FAST-TRANSIENT-RESPONSE 500-mA LOW-DROPOUT VOLTAGE REGULATORS SGLS010B − MARCH 2003 − REVISED JUNE 2010 D Controlled Baseline − One Assembly/Test Site, One Fabrication Site D Extended Temperature Performance of −55°C to 125°C D Enhanced Diminishing Manufacturing Sources (DMS) Support D Enhanced Product Change Notification D Qualification Pedigree† D Open Drain Power-On Reset With 200-ms Delay D 500-mA Low-Dropout Voltage Regulator D Available in 1.5-V, 1.6-V, 1.8-V, 2.5-V, 3.3-V Fixed Output and Adjustable Versions D Dropout Voltage to 169 mV (Typ) at 500 mA (TPS77533) † Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range.

This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life.

Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits.

Key Features

  • a sleep mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to 1 μA at TJ = 25°C. The RESET output of the TPS775xx initiates a reset in microcomputer and microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS775xx monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage. The TPS775xx is offered in 1.5-V, 1.6-V, 1.8-V, 2.5-V, and 3.3-V fixed-vol.
