Voltage Regulators - Linear, Low Drop Out (LDO) Regulators datasheet and documents for KA7915ATU

KA7915ATU

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

The KA7915ATU is a three-terminal negative voltage regulator from the KA79XXA series, manufactured by onsemi. It provides a fixed output voltage of -15 V with a tolerance of ±2%. The device supports an output current in excess of 1 A and operates within a junction temperature range of 0 to +125 °C. It utilizes a TO-220 package for through-hole mounting. Key electrical characteristics include a maximum input voltage of -35 V, a typical ripple rejection of 60 dB at 120 Hz, and a quiescent current of 3 to 6 mA.
