## Description

This compact CMOS regulator provides a fixed 3.3V single output for low-current electronics projects and embedded hardware. It is rated for up to 200mA output current and is intended for surface-mount designs.The regulator includes an on/off control input, making it suitable for circuits that need enable control or low-power switching. It is designed for low dropout voltage, low output noise voltage and fast load transient response.Built-in protection and discharge functions help simplify power rail design, with overcurrent protection and an Auto-discharge function included. A manufacturer datasheet is available for detailed application guidance.Features:CMOS single output voltage regulatorOn/off control inputLow dropout voltageLow output noise voltageFast load transient responseOvercurrent protectionAuto-discharge functionSpecifications:Output Type: FixedNumber of Regulators: 1Voltage - Input (Max): 5.5VVoltage - Output (Min/Fixed): 3.3VVoltage Dropout (Max): 0.2V @ 150mACurrent - Output: 200mACurrent - Quiescent (Iq): 60µAPSRR: 73dB (1kHz)Control Features: EnableProtection Features: Over CurrentOperating Temperature: -40°C ~ 85°CMounting Type: Surface MountMfg #: TCR2EF33A useful fixed 3.3V regulator for compact PCB designs, sensor supplies and low-power embedded circuits.
