TPS767D301-EP

增强型产品双路输出、低压降稳压器

The dual-voltage regulator offers fast transient response, low dropout LDO voltages, and dual outputs in a compact package and incorporates stability with 10-µF low-ESR output capacitors.

The TPS767D301-EP dual-voltage regulator is designed primarily for DSP applications. This device can be used in any mixed-output voltage application, with each regulator supporting up to 1 A. Dual active-low reset 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 and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading typically 85 µA over the full range of output current, 0 mA to 1 A. These two key specifications yield a significant improvement in operating life for battery-powered systems. This LDO device also features a sleep mode; applying a TTL high signal to enable EN shuts down the regulator, reducing the quiescent current to 1 µA at TJ = 25°C.

The RESET output of the TPS767D301-EP initiates a reset in microcomputer and microprocessor systems in the event of an undervoltage condition. An internal comparator in the TPS767D301-EP monitors the output voltage of the regulator to detect an undervoltage condition on the regulated output voltage.

The TPS767D301-EP is offered 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 3% over line, load, and temperature ranges. The TPS767D301-EP is available in a 28-pin PWP TSSOP package. The device operates over a junction temperature range of –55°C to 125°C.
