TA78L009AP,F(J

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

The TA78L009AP is a three-terminal positive linear regulator from Toshiba Semiconductor and Storage, providing a fixed 9V output. It supports a maximum output current of 150 mA at 25°C junction temperature. The device operates with an input voltage range up to 35 V and features internal overcurrent and overheating protection mechanisms. Electrical characteristics include a typical dropout voltage of 1.7 V at 40 mA and a ripple rejection ratio of 44 dB at 120 Hz. It is housed in a plastic TO-92MOD (LSTM) package suitable for through-hole mounting.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify RoHS compatibility status directly with Toshiba sales representatives as environmental compliance varies by production lot. Confirm package type availability since the product may be discontinued or subject to specific ordering suffixes. Ensure system design accounts for absolute maximum ratings to prevent permanent damage during overload conditions.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 9V output is required with moderate current demands up to 150 mA. Consider the 1.7 V dropout voltage to ensure sufficient input-output differential. Verify that the application environment stays within the -30°C to 85°C operating temperature range. Evaluate thermal dissipation requirements given the 800 mW power dissipation limit at 25°C ambient.
