ISL78302ARFWZ-T

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

The ISL78302ARFWZ-T is a dual-channel automotive-grade low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It provides two fixed output voltages of 1.2 V and 2.5 V, each capable of delivering up to 300 mA of output current. The device operates with an input voltage range from 2.3 V to 6.5 V and features a typical power supply rejection ratio (PSRR) of 64 dB. Quiescent current is specified at 47 µA, with a maximum dropout voltage of 300 mV at full load. It is housed in a 10-lead DFN package and supports an operating temperature range from -40°C to +105°C.

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

Dual-output configuration providing independent 1.2 V and 2.5 V rails for simultaneous power requirements.
High power supply rejection ratio (PSRR) ensures stable operation in electrically noisy environments.
Automotive qualification compliant with AEC-Q100 standards for reliability in vehicle applications.
Integrated protection mechanisms including overcurrent limiting and thermal shutdown.

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

Powering sensitive analog circuits in automotive infotainment systems

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

Verify the specific suffix against official Renesas documentation to confirm tape-and-reel packaging versus tube variants. Confirm end-of-life status as the standard ISL78302ARFWZ has been marked obsolete. Ensure compatibility with moisture sensitivity level 3 requirements during assembly. Cross-reference pinouts with the latest datasheet revision to avoid integration errors.

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

Select this component when dual isolated LDO outputs are required within a single footprint. The fixed 1.2 V and 2.5 V outputs eliminate external resistor networks. Verify that the input voltage remains above the minimum threshold of 2.3 V under all operating conditions. Consider the 300 mA per channel limit when designing for peak load scenarios.

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