TLV1117CDCYR

Texas Instruments · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · SOT-223-4

TLV1117CDCYR from Texas Instruments, in a SOT-223-4. 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 ADJ input Adjust pin for the adjustable-output variant (TLV1117CDCYR). Output voltage is set by an external resistor divider from OUT to ADJ to GND, referenced to VREF = 1.25 V (typ). ADJ pin current is 80 µA typ (120 µA max); change in ADJ pin current is 0.2 µA typ (5 µA max for C-temp) over VIN-VOUT = 1.4 V to 10 V and IOUT = 10 mA to 800 mA. On fixed-voltage TLV1117-xx options this pin becomes GND.
2 OUT power_out Regulated output pin. Provides up to 800 mA. Requires an output capacitor (typ 10 µF tantalum or aluminum electrolytic) with ESR between 0.2 Ω and 10 Ω for stability. Internally tied to pin 4 (tab).
3 IN power_in Unregulated input supply. Recommended operating range for the adjustable TLV1117 is 2.7 V to 15 V; absolute maximum VIN is 16 V. A 10-µF input capacitor is recommended.
4 OUT power_out Thermal tab / large pad; internally connected to the OUT pin (pin 2). Must be soldered to a copper area to spread heat - the DCY package has θJA ≈ 104.3 °C/W. Connect to the same net as pin 2 (VOUT).
