Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for ISL9021IRUYZ-T

ISL9021IRUYZ-T

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

The ISL9021IRUYZ-T is a fixed-output linear low-dropout (LDO) voltage regulator manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 0.9V with a maximum continuous load current of 250mA. The device supports an input voltage range up to 5.5V and features a typical dropout voltage of 150mV at full load. Key electrical parameters include a quiescent current of 50µA, power supply rejection ratio (PSRR) ranging from 60dB to 50dB across frequencies of 1kHz to 1MHz, and an output accuracy of 0.8%. It operates within a temperature range of -40°C to +85°C.

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

Portable battery-powered equipment
Wireless communication devices
Low noise analog circuits requiring stable power supplies

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

Verify component authenticity as the ISL9021 series has received End-of-Life (EOL) notices from Renesas. Confirm specific package markings and lot codes against official datasheets. Check for RoHS3 compliance status in current inventory sources. Ensure replacement strategies are evaluated due to discontinuation status.

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

Select this part for applications requiring a precise 0.9V fixed output from a higher input rail. Consider the 250mA current limit and 5.5V maximum input voltage constraints. Evaluate thermal dissipation requirements based on the voltage drop and load current. Verify compatibility with 1µF output capacitance for stability.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

The ISL9021 series consists of single LDO regulators designed for low noise and high PSRR applications. Variants differ primarily by fixed output voltage settings while sharing common packaging in 6-UTDFN (1.6x1.6) format. The series targets portable electronics where efficiency and space saving are critical.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Official EOL notices indicate discontinuation. Potential substitutes must match 250mA output, 0.9V fixed voltage, and 6-UTDFN package. Verify pinout compatibility and thermal characteristics before integration.
