SLVS209H – JULY 1999 – REVISED AUGUST 2008 DUAL-OUTPUT LOW-DROPOUT VOLTAGE REGULATORS FEATURES 1 23 Dual Output Voltages for Split-Supply Applications Output Current Range of 0mA to 1.0A per Regulator 3.3V/2.5V, 3.3V/1.8V, and 3.3V/Adjustable Output Fast-Transient Response 2% Tolerance Over Load and Temperature Dropout Voltage Typically 350mV at 1A Ultra-low 85µA Typical Quiescent Current 1µA Quiescent Current During Shutdown Dual Open-Drain Power-On Reset with 200ms Delay for Each Regulator 28-Pin PowerPAD™ TSSOP Package Thermal Shutdown Protection for Each Regulator DESCRIPTION The TPS767D3xx family of dual voltage regulators offers fast transient response, low dropout voltages and dual outputs in a compact package and incorporating stability with 10µF low ESR output capacitors. The TPS767D3xx family of dual voltage regulators is designed primarily for DSP applications. These devices can be used in any mixed-output voltage application, with each regulator supporting up to 1A. Dual active-low reset signals allow resetting of core-logic and I/O separately. Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (350mV typically at an output current of 1A for the TPS767D325) and is directly proportional to the output current. Additionally, since the...
