PT7M8218B33CE

PT7M8218B33CE Description

The PT7M8218B33CE is a linear voltage regulator designed by Diodes Incorporated, offering a fixed output voltage of 3.3V and a maximum output current of 300mA. This regulator is designed for surface mount applications and comes in a compact SC70-5 package. It features a low dropout voltage of 0.15V at 150mA, ensuring efficient power delivery even at low input voltages. The regulator is equipped with an enable control feature, allowing for dynamic power management, and includes over-current and over-temperature protection to safeguard against potential faults. Despite its small form factor, the PT7M8218B33CE maintains a high power supply rejection ratio (PSRR) of 75dB at 1kHz, minimizing noise and ripple in the output voltage. With a quiescent current of only 50 µA, this regulator is well-suited for low-power applications. The PT7M8218B33CE is REACH unaffected and RoHS3 compliant, ensuring environmental sustainability and regulatory compliance. Although the product is now obsolete, its robust design and performance make it a reliable choice for existing applications.
