TPS76901SHKJ

TPS76901SHKJ is a Texas Instruments low-dropout regulator (LDO) in the TPS7690x family. It provides a stable output from a higher input voltage for compact, battery-powered or portable electronics.
Key points:
- Fixed-output LDO variant (the exact Vout depends on the specific device; check the datasheet for available voltages).
- Small footprint and low quiescent current, suitable for power rails in microcontrollers and sensors.
- Protections such as thermal/shutdown and current limit are typically included; some devices have an enable pin.
- Available in small packages (suffix SHKJ indicates package/temperature Grade; see TI catalog for exact package).
- Requires input and output capacitors per the datasheet for stability and best transient response.
How to use:
- Choose the fixed Vout variant you need.
- connect VIN to your source, VOUT to the load, and place the recommended input/output capacitors.
- tie EN high if your variant has an enable pin.
For exact electrical specs, pinout, and package details, refer to the TPS76901SHKJ datasheet and TI product page.

Here are the key features of TI TPS76901SHKJ (highlights):
- Fixed-output low-dropout regulator (LDO) with enable pin
- Wide input voltage range (suitable for 1.8–5.5 V supply rails)
- Stable with ceramic output capacitors (low ESR) for compact designs
- Protections: overcurrent/short-circuit protection and thermal shutdown
- Reverse-current protection (output-to-input protection)
- Low quiescent current for battery-powered applications
- Fast transient response and good line/load regulation
- Temperature range suitable for most consumer/battery environments
- Package option SHKJ (TI’s SOT-23/-5 style package) with standard automotive/industrial temp grades
Note: Exact output voltage options and current rating depend on the specific device variant used (the “01” indicates the fixed-output variant within the TPS7690x family).

SOT-23-5 (SC-70-5), a 5-pin package.

- Pin count: 3 pins
- Function: Three-terminal fixed-output low-dropout (LDO) regulator (VIN, VOUT, GND) from TI, used to regulate input voltage to a stable output voltage.

- Manufacturer: Texas Instruments (TI).
- What kind of company: American multinational technology company that designs and manufactures semiconductors and integrated circuits, specializing in analog, mixed-signal, and power-management ICs.

TPS76901SHKJ is a low-noise, low-quiescent current LDO suitable for compact, battery-powered systems. Common application areas include:
- Battery-powered portable devices and wearables
- IoT sensors and wireless modules
- Microcontroller/DSP/FPGA core supplies, memory, and sensor rails
- Cameras, image sensors, and display subsystems
- Medical and industrial equipment needing compact, stable power rails

Exact equivalents depend on matching specs (Vout, Iout, Vin range, dropout, package, temp range). TPS76901SHKJ is a fixed LDO; to cross-reference, please provide:
- Vout (likely 1.0 V)
- Max Iout
- Vin max/min
- dropout voltage
- package (e.g., SOT-23-5)
- temperature range
