ISL60002DIH312Z-TK

Product Overview

The Renesas Electronics Corporation ISL60002DIH312Z-TK is a fixed series voltage reference intended for compact surface-mount power management and analog reference tasks. It provides a 1.25 V output from a 2.7 V to 5.5 V input and supports 7 mA output current. The device combines a ±0.4% tolerance, a 20 ppm/°C temperature coefficient, and 30 µVp-p noise in the 0.1 Hz to 10 Hz band, supporting stable biasing and measurement reference functions. Its 900 nA supply current and SOT-23-3 package make it suitable for board layouts where a small, low-current reference is needed across the -40°C to 85°C operating temperature range.

Key Features

• Series reference type with fixed 1.25 V output
• Output tolerance of ±0.4% and temperature coefficient of 20 ppm/°C
• Noise of 30 µVp-p in the 0.1 Hz to 10 Hz band
• Input voltage range of 2.7 V to 5.5 V
• Output current capability of 7 mA
• Supply current of 900 nA
• Operating temperature range of -40°C to 85°C (TA)
• Surface-mount TO-236-3, SC-59, SOT-23-3 package

Applications

• Fixed reference for analog-to-digital converter front ends operating from 2.7 V to 5.5 V supplies
• Stable biasing point for sensor conditioning or signal-chain circuits using a 1.25 V reference
• Compact voltage reference in low-current measurement and control boards where 900 nA supply current is relevant

Design & Procurement Notes

Designers should verify that the system supply remains within 2.7 V to 5.5 V and that load current requirements are compatible with the 7 mA output current specification. The fixed 1.25 V output, ±0.4% tolerance, 20 ppm/°C coefficient, and 30 µVp-p 0.1 Hz to 10 Hz noise should be evaluated together against the accuracy budget of the ADC or sensor interface. The 900 nA supply current is relevant for quiescent-power planning, while the SOT-23-3 surface-mount package and -40°C to 85°C operating range support compact board layouts within that temperature envelope. When specifying the part, use the exact manufacturer part number ISL60002DIH312Z-TK to preserve the fixed 1.25 V output and SOT-23-3 package.
