Detailed Description

Low-dropout linear regulator, fixed 3.0 V output. Designed for portable and battery-powered systems where clean, stable power is needed. Low noise, high PSRR, and low quiescent current for efficient, quiet operation. Enable control for simple on or off. Integrated protection for safe use. Stock on hand 2550 units. Date code 07+ indicates mature production vintage.

Key Features

Fixed 3.0 V output setpoint for the -3030 variant

Low dropout at typical loads for stable output near battery voltage

High PSRR to reduce ripple and noise from the input supply

Low output noise, supports bypass capacitor for extra filtering

Low quiescent current for better battery life

Enable pin for easy power sequencing

Integrated current limit and thermal shutdown

Wide input voltage range typical of the LP398x family

Output accuracy typically within a tight tolerance window

Surface mount package for compact designs

Key Advantages

Clean 3.0 V rail for noise-sensitive circuits

Simple power architecture with few external parts

Reliable protection features reduce design risk

Efficient operation improves battery runtime

Straightforward drop-in for many 3.0 V rails

Backed by TI quality and Y-IC distribution support

Packaging

Type surface-mount plastic IC package

Material molded epoxy encapsulation with copper leadframe

Size code 3048 typically aligns to an approximate 3.0 mm by 4.8 mm body footprint as listed. Confirm exact mechanical drawing in the datasheet

Pin configuration typical of an LDO regulator. Common pins are VIN, VOUT, GND, EN, and BYPASS. Pin count depends on the exact sub-variant. Confirm with the datasheet

Thermal characteristics include integrated thermal shutdown. Thermal performance depends on PCB copper area and layout. Follow the layout guidelines for best heat dissipation

Electrical properties typical of the LP398x family. Input voltage range around low to mid single-digit volts, low dropout in the hundreds of millivolts at rated load, high PSRR, tight output accuracy, low noise with a bypass capacitor. Exact numbers vary by sub-variant and must be verified in the datasheet

Lifecycle

Mature product. The 07+ date code indicates earlier production, so availability may vary by lot and finish

If you need long-term supply or newer alternatives, we can suggest equivalent or functionally similar parts. Examples from Texas Instruments include LP5907-3.0, TPS73230, TPS71730, TLV70030, TPS73530, TPS7A02-3.0, TPS7A05-3.0. Suitability depends on your required current, noise, PSRR, and package

For true drop-in form fit function replacement, confirm pinout and characteristics in the datasheet. If an exact equivalent is not listed for your layout, please contact our sales team via the Y-IC website for detailed cross support and lifecycle status
