ISL9011IRCJZ-T

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

The ISL9011IRCJZ-T is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides two fixed output voltages: Channel 1 outputs 1.8V at a maximum current of 150mA, and Channel 2 outputs 2.8V at a maximum current of 300mA. The device operates with an input voltage range of 2.3V to 6.5V. Key electrical specifications include a typical quiescent current of 45µA when both channels are active, a shutdown current below 0.1µA, and a power supply rejection ratio (PSRR) of 70dB at 1kHz. The unit features ±1.8% output voltage accuracy and is housed in a 10-lead 3mm x 3mm Dual Flat No-Lead (DFN) package.

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

Verify the specific ordering suffix '-T' indicates tape and reel packaging configuration as defined in manufacturer technical briefs. Confirm that the part marking 'DBVA' corresponds to the 1.8V/2.8V voltage combination. Ensure compliance with RoHS standards and verify moisture sensitivity level classifications prior to assembly.

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

Select this component for applications requiring simultaneous generation of 1.8V and 2.8V rails from a single input source. Evaluate stability requirements against the specified 1µF to 10µF output capacitance range with ESR limits up to 200mΩ. Consider the 10-lead DFN package dimensions for PCB layout constraints and thermal dissipation needs within the -40°C to +85°C operating temperature range.
