Overview

The ISL21010 is a precision, low dropout micropower bandgap voltage reference in a space-saving SOT-23 package. It operates from a single 2.2V to 5.5V supply (minimum voltage is dependent on voltage option) and provides a ±0. 2% accurate reference. The ISL21010 provides up to 25mA output current sourcing with low 150mV dropout voltage. Output voltage options include 1.024V, 1.2V, 1.5V, 2.048V, 2.5V, 3.0V, 3.3V, and 4.096V. The low supply current and low dropout voltage combined with high accuracy make the ISL21010 ideal for precision battery powered applications.

  1. decode marking

    Hi, we have the part ISL21010CFH325Z-TK which top marking showing "GDDL", which is not the part marking. would you help decode for it. And, can we trace the DC at the code, thanks [locked by: Michael Quirk at 20:55 (GMT 0) on 19 Jan 2023]

  2. RENESAS (ISL21010DFH310Z-T7A) SMD code???

    I bought this component RENESAS (ISL21010DFH310Z-T7A) and on the datasheet we must have the SMD code BEBA but we have GCRP. Is that normal?
