DescriptionThe TPS767D301-Q1 dual voltage regulators offers fast transient response, low dropout voltages and dual outputs in a compact package and incorporating stability with 10-F low ESR output capacitors.
The TPS767D301-Q1 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 1 A. Dual active-low reset signals allow resetting of core-logic and I/O separately.
Because the PMOS device TPS767D301-Q1 behaves as a low-value resistor, the dropout voltage is very low (typically 350 mV at an output current of 1 A for the TPS767D325) and is directly proportional to the output current. Additionally,since the PMOS pass element is a voltage-driven device, the quiescent current of TPS767D301-Q1 is very low and independent of output loading (typically 85 A over the full range of output current, 0 mA to 1 A). These two key specifications of TPS767D301-Q1 yield a significant improvement in operating life for battery-powered systems. This LDO family also features a sleep mode; applying a TTL high signal to EN (enable) shuts down the regulator, reducing the quiescent current to 1 A at TJ = 25°C.
The RESET output of the TPS767D301-Q1 initiates a reset in microcomputer and microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS767D3xx monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage.
The TPS767D301-Q1 is offered in 1.8-V, 2.5-V, and 3.3-V fixed-voltage versions and in an adjustable version (programmable over the range of 1.5 V to 5.5 V). Output voltage tolerance is specified as a maximum of 2% over line, load, and temperature ranges. The TPS767D301-Q1 is available in 28 pin PWP TSSOP package. They operate over a junction temperature range of −40°C to 125°C.
