Manufacturer Part Number

LP2985AITP-2.6/NOPB

Description

This is a fixed, low-dropout linear voltage regulator that delivers a steady 2.6V output with up to 150mA current. It is designed for battery-powered equipment, portable devices, and applications needing low noise and power consumption. The enable feature allows for power saving control. Over-current, over-temperature, and short circuit protection increase device reliability. The 5-DSBGA package is very compact, ideal for space-limited designs.

Device Structure

This IC is a single-channel, positive voltage, fixed regulator. It is built with integrated enable control and protection circuits. The silicon die is packaged in a 5-ball DSBGA for minimal footprint, suitable for compact PCBs.

Performance Characteristics

Very low dropout voltage enables efficient operation on low input voltages. Low quiescent current helps extend battery life. The device maintains 2.6V output within load and line regulation specs. Integrated protection features safeguard both the IC and the end system during faults.

Application Environments

Suited for portable and battery-powered applications, such as smartphones, handheld instruments, sensor modules, and small form factor electronics. Can be used in industrial, consumer, and IoT devices that require stable, low-voltage rails.

Selection Guidelines

Pick this regulator for applications needing a 2.6V supply, current up to 150mA, and low quiescent current. Ensure the input voltage stays between the required output + dropout up to 16V max. Choose the DSBGA package where PCB space is tight or height/volume is constrained.

Usage Considerations

Do not exceed voltage and current ratings to prevent damage. Solder properly to ensure good thermal and electrical performance. Protect against input surges. Provide adequate PCB heat dissipation according to power loss. Use enable pin for system power control. This model is now obsolete—future designs should use alternatives.
