LTP7293:3A output, Low Vin, Low Noise Linear Regulator


The LTP7293 is a low VIN, low noise linear regulator with typical 30 mV ultra-low dropout voltage. The LTP7293 could support very low input voltage supply range from 1.1 V to 1.98 V with no external bias supply required. It is also designed to support both fixed output voltage and adjustable output voltage range from 0.5 V to 1.5 V.

Excellent power supply rejection ratio (PSRR) and low noise performance can limit the phase noise and clock jitter generated by the power supply, together with 3 A maximum output current capability and connecting a capacitor to SS pin to program soft-start time externally, it makes LTP7293 ideal power supply for mainly two types of applications---One is digital-loads, such as Field-programmable gate array (FPGA) and digital signal processor (DSP) supplies. The other is for noise sensitive applications, such as RF transceivers, high performance Serializer / DeSerializer (Serdes), analog-to-digital converter (ADC) and digital-to-analog (DAC) circuits.

The LTP7293 is available in 3 mm × 3 mm QFN-16L packages. It is rated over −40℃ to +125℃ extended industrial temperature range.
