TPS70158PWP

TPS70158PWP is a fixed-output, low-dropout voltage regulator from TI’s TPS701x family. It provides a stable supply rail (commonly 1.8 V) from a higher input voltage for microcontrollers, memories, and other peripherals in battery-powered or space-constrained designs. Key features typically include low quiescent current, low dropout, an enable pin to shut the device off when not needed, and protection functions such as short-circuit and thermal protection. The PWP suffix designates a compact TI package option suitable for small-board applications. Applications: portable electronics, wearables, IoT sensors, and any system needing a quiet, efficient 1.8 V (or the specified fixed output) rail. For exact output voltage, input range, quiescent current, dropout, and pinout, consult the TPS70158PWP datasheet and product page.

TPS70158PWP features (concise):
- Low-dropout linear regulator for up to ≈150 mA output
- Ultra-low quiescent current (microamps) with very low shutdown current
- Enable (EN) input to turn the regulator on/off
- Very low dropout voltage (typical tens to hundreds of mV at moderate load)
- Wide input range (up to about 6 V)
- Overcurrent/short-circuit protection and thermal shutdown
- Small PWP package for compact PCB mounting
Note: values are typical; please refer to the TI datasheet for exact numbers and fixed/adjustable options.

- Pin count: 8 pins (PWP package, WQFN-like).
- Function: Ultra-low-quiescent-current fixed-output LDO regulator (TPS70158 family) with a fixed output of 1.58 V; features include an enable (EN) input and a bypass (BYP) option; pins typically include VIN, VOUT, GND, EN, BYP, plus three No-Connects.

- Manufacturer: Texas Instruments (TI)
- What kind of company: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits.

TPS70158PWP is a fixed 1.58-V low-dropout regulator. Typical application areas include:
- Core/logic power rails for microprocessors, DSPs, FPGAs, and other digital ICs
- Memory core voltages
- Battery-powered portable devices, wearables, and IoT sensors
- Compact consumer electronics requiring a precise, low-noise 1.58-V supply
- Post-regulation in PMICs for digital/RF front-end sections where a stable 1.58-V rail is needed
