ISL80102IR18Z-T

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

The ISL80102IR18Z-T is a fixed-output linear regulator from the ISL80102 series, manufactured by Renesas Electronics Corporation. It provides a fixed positive output voltage of 1.8V with a maximum continuous output current of 2A. The device operates within an input voltage range of 2.2V to 6V and utilizes a 10-DFN (3x3 mm) surface-mount package with an exposed pad. Key electrical specifications include a quiescent current of 9 mA and a maximum supply current of 12 mA. Power supply rejection ratio (PSRR) ranges from 62 dB at 120 Hz to 55 dB at 1 kHz. The component supports operation across an extended temperature range of -40°C to +125°C.

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

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration as per manufacturer documentation. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Check for obsolescence notices or product change notifications (PCN) affecting this part number. Ensure the ordering code matches the fixed 1.8V output variant rather than adjustable versions.

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

Select this component when a compact 2A LDO with low quiescent current is required for space-constrained designs. The 1.8V fixed output suits digital logic families operating at this voltage level. Consider the 10-DFN package for thermal performance and board space optimization. Verify that the input voltage remains above the dropout threshold for the desired load current.

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

This part belongs to the ISL80102/ISL80103 family of high-performance linear regulators designed for low-voltage, high-current applications. The ISL80102 specifically targets 2A output currents, while the ISL80103 handles up to 3A. Both utilize sub-micron BiCMOS processes to achieve low dropout voltages and high efficiency in portable electronics.
