DI78L09DAB

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

The DI78L09DAB is a positive fixed voltage linear regulator from Diotec Semiconductor, housed in an SO-8 surface-mount package. It provides a nominal output of 9 V with a tolerance of ±5%, ranging from 8.64 V to 9.36 V. The device supports a maximum output current of 100 mA and operates within a junction temperature range of -40°C to +125°C. Maximum input voltages vary by output rating, reaching up to 30 V for the 9 V version. Key electrical parameters include a quiescent current of 6 mA, line regulation of 225 mV, load regulation of 80 mV, and ripple rejection of 44 dB at 120 Hz.
