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

Verify that the specific ordering suffix HSQ corresponds to the SC-70 package variant rather than the SOT-23 configuration. Confirm the 'H' designation indicates the standard output discharge feature rather than the auto-discharge version. Ensure compliance with RoHS directives and check for any end-of-life notifications or alternative part recommendations from the manufacturer before finalizing procurement plans.

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

Select this component when a precise 1.5 V rail is required from a single-cell or dual-cell battery source. The SC-70 package offers space efficiency for compact portable designs. Consider the quiescent current specifications for battery life optimization. Verify that the input voltage never exceeds the absolute maximum rating during transient events to maintain reliability.

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

This part belongs to the NCP4620 series of 150 mA CMOS linear regulators. The series provides various fixed output voltages ranging from 1.2 V to 6.0 V. Variants are available in both SOT-23 and SC-70 packages, with options for standard or auto-discharge output configurations. The series is designed for applications requiring high line regulation and low noise performance.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

NCP4620DSQ15T1G: Offers identical electrical performance but includes an auto-discharge feature for faster output capacitor discharge upon shutdown. NCP4620HSN15T1G: Provides the same 1.5 V output and protection features but utilizes the SOT-23-5 package instead of SC-70.
