TL780-15CKC

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The TL780-15CKC is a positive-voltage linear regulator from the Texas Instruments TL780 series, housed in a TO-220 (KC) package. It provides a fixed output voltage of 15 V with an output current capability of 1.5 A. The device features ±1% output tolerance at 25 °C and ±2% over the full operating temperature range. Recommended input voltage ranges from 17.5 V to 30 V. Internal protections include short-circuit current limiting and thermal shutdown.
