NCP7906CTG

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

The NCP7906CTG is a fixed negative linear voltage regulator from onsemi, delivering a stable -6 V output at up to 1 A. It operates within an input voltage range of -7.3 V to -35 V and maintains performance across a junction temperature range of 0 °C to +125 °C. Key electrical characteristics include a typical line regulation of 120 mV, load regulation of 120 mV, and a power supply rejection ratio (PSRR) of 65 dB. The device features a quiescent current of approximately 4.3 mA and is housed in a TO-220-3 through-hole package.
