Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for ISL9021IRUMZ-T

ISL9021IRUMZ-T

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

The ISL9021IRUMZ-T is a fixed-output linear low-dropout (LDO) voltage regulator manufactured by Renesas Electronics. It provides a fixed output voltage of 3 V with a maximum continuous output current of 250 mA. The device operates within an input voltage range of 1.5 V to 5.5 V and features a typical dropout voltage of 150 mV at full load. It incorporates comprehensive protection mechanisms including overcurrent, thermal shutdown, reverse polarity, short-circuit, and soft-start capabilities.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Feature Summary

Integrated reverse current protection prevents backflow from the output to the input, ensuring system safety in WLCSP and µTDFN package configurations.
High power supply rejection ratio (PSRR) performance maintains stable regulation against input line noise across varying frequency ranges.
Low quiescent current operation supports extended battery life in portable applications while maintaining precise voltage regulation.

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

Portable electronic devices requiring efficient power management
Battery-powered systems needing low-noise voltage regulation
Embedded circuits utilizing single-supply architectures

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

Verify component authenticity through authorized distributors as this part may be subject to obsolescence notices. Confirm package integrity upon receipt, as surface-mount components are sensitive to moisture and physical damage. Cross-reference datasheet revisions to ensure compatibility with existing design specifications before final procurement decisions.

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

Select this regulator when a fixed 3 V output is required with moderate current demands up to 250 mA. Ensure the input voltage remains within the specified 1.5 V to 5.5 V range for optimal performance. Consider the thermal characteristics and PCB layout requirements associated with the UTDFN-6 package for adequate heat dissipation during continuous operation.

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

This component belongs to the ISL9021A series of single LDO regulators designed for low noise and high PSRR applications. The series offers various output voltages and package options, including WLCSP and µTDFN formats. It is engineered for use in space-constrained designs where efficiency and signal integrity are critical parameters.

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

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that match the 3 V output and 250 mA current rating. Verify that any substitute maintains identical protection features and package dimensions to ensure seamless integration without redesigning the printed circuit board.
