PARAMETRIC INFO
• Output voltage: 3.3 V (fixed).
• Maximum output current: 150 mA.
• Input voltage range: 0 V to 6.0 V (absolute usable input range; follow datasheet recommendations for proper operation).
• Typical dropout voltage: ~90–100 mV at light loads (see datasheet graphs for exact values at different currents and temperatures).
• Quiescent (ground) current, Iq: typical ~40 µA (some listings show up to 100 µA as a maximum or under certain conditions —check the datasheet/test conditions).
• Line / load regulation: Designed for good regulation and stability with recommended output capacitor; refer to datasheet for numerical graphs.
• Protection features: Internal current limiting and thermal shutdown.
• Enable (EN) pin: Device includes an enable input for power sequencing and low-power shutdown control.


PACKAGE INFO
• Package type: TSOP-5 (5-lead TSOP / 5-pin flat package), surface-mount. Typical distributor listings show “5-TSOP” / “TSOP-5”.
• Mounting: SMD (solderable footprint, automatic pick-and-place friendly).
• Packaging options: Tape & reel, cut tape (depending on supplier).


APPLICATIONS
• Battery-powered equipment and handheld devices (camera modules, portable communications gear).
• Consumer electronics and embedded systems that require a compact 3.3 V regulator with low standby current.
• Power rails for small microcontrollers, sensors, and analog front-ends where up to 150 mA is sufficient.
