NCP552SQ27T1

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

The NCP552SQ27T1 is a fixed-output NOCAP linear voltage regulator from onsemi, providing a nominal 2.7 V output with an 80 mA maximum current capability. It features ultra-low quiescent current of 2.8 µA typical and operates within an industrial temperature range of -40°C to +85°C. The device includes an enable pin for power control, internal thermal shutdown, and overcurrent protection. Packaged in the micro-miniature SC82-AB (SC70-4) surface-mount format, it supports low-cost ceramic capacitors and can operate without an output capacitor under specific conditions.

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

Verify the component status as obsolete or end-of-life through official manufacturer channels before finalizing procurement plans. Confirm RoHS compliance and material declarations via the latest datasheet revision. Ensure design compatibility with the SC82-AB package dimensions and electrical specifications for the target application environment.

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

Select this regulator when low static current and compact footprint are critical for portable designs. The NCP552 variant is required if hardware-based enable/disable functionality is needed, distinguishing it from the NCP553 which lacks this pin. Verify that the input voltage remains within the 12 V absolute maximum rating while ensuring adequate thermal dissipation for the expected load current and ambient temperature conditions.

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

This component belongs to the NCP552/553 series of NOCAP CMOS low dropout regulators designed for handheld communication equipment. It shares architectural similarities with the NCP553 but adds an enable pin for power management. The series utilizes a PMOS power transistor and integrates reference, error amplifier, and protection circuits into a single micro-package.
