XC6501D28A7R-G

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The XC6501D28A7R-G is a fixed-output low-dropout (LDO) voltage regulator manufactured by Torex Semiconductor. It provides a stable 2.8 V output with a maximum continuous current of 200 mA. The device operates within an input voltage range of 1.4 V to 6 V and maintains a typical dropout voltage of 150 mV at full load. Quiescent current is specified at 13 µA, ensuring efficient power management in battery-powered applications. The regulator features a high power supply rejection ratio (PSRR) of 50 dB and offers precise voltage regulation accuracy of 1%. It is housed in a compact USPN-4 surface-mount package and is rated for operation across a temperature range of -40°C to +85°C.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'A7R' corresponds to the USPN-4 package and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure input voltage does not exceed the 6 V maximum rating to prevent device damage. Check thermal dissipation requirements based on ambient temperature and load current to maintain safe operating junction temperatures.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 2.8 V output is required with minimal external components. It is suitable for applications prioritizing low static current and small footprint over ultra-high precision or high-current capabilities. Compare against other XC6501 variants if different output voltages or package types are needed. Consider thermal performance if operating near maximum current limits.
