TSM101AIDT

STMicroelectronics · Voltage Reference · SOP-8

TSM101AIDT from STMicroelectronics, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Vref output Voltage Reference Output: 1.24V, 10mA max. Do not short circuit. Provides the internal band-gap reference to external circuitry.
2 Csen input Current source enable input. The internal current source is enabled when the voltage on pin 2 is lower than 0.8V; used to offset the voltage measured on the sense resistor to modify the charge current.
3 Crref input Current Limitation Reference Input. Non-inverting input of the current limitation loop op-amp; typically tied to a resistor bridge that sets the current limit threshold.
4 GND power_in Ground / network reference. All voltages in the datasheet are given with respect to this pin.
5 Crin input Current Limitation Loop Input, connected to the sense resistor. Inverting input of the current limitation op-amp that senses load current.
6 OUTPUT output Output pin common to the voltage regulation and current limitation loops (ORed open-collector-style output). Can drive the primary-side LED of an optocoupler for isolated feedback to a PWM controller.
7 Vrin input Voltage Regulation Loop input. Inverting input of the voltage regulation op-amp; typically driven from a resistor divider sampling the output voltage.
8 VCC power_in Power supply input, 4.5V to 32V DC (absolute max 36V). Typical total supply current 2mA max at VCC=1.5V.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: STMicroelectronics datasheet (13 pp, sha256 d54997d5346d0878, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
