L78L09ABD13TR

Overview

The L78L09ABD13TR is a three-terminal positive linear voltage regulator from the STMicroelectronics L78L series, housed in an SO-8 surface-mount package. It provides a fixed output voltage of 9 V with a maximum output current capability of 100 mA. The device features internal current limiting and thermal shutdown protection, ensuring robust operation under fault conditions. It operates within a junction temperature range of -40 °C to +125 °C and supports a maximum DC input voltage of 30 V. The quiescent current is typically 6 mA at 25 °C.

Feature Summary

Integrated short-circuit and thermal overload protection mechanisms enhance device reliability.
Requires no external components for basic fixed voltage regulation applications.
Designed for local or on-card regulation to eliminate noise associated with single-point distribution.

Applications

Local or on-card voltage regulation
Replacement for Zener diode/resistor combinations
Power pass element configuration for high-current regulators

Procurement Notes

Verify the specific suffix 'D13TR' corresponds to the SO-8 tape-and-reel packaging format required for automated assembly processes. Confirm that the AB designation aligns with the required ±4% output voltage tolerance specification for the target application design constraints.

Selection Notes

Select this component when a fixed 9 V output is required with a maximum load current of 100 mA in a compact surface-mount form factor. Ensure the input voltage remains within the 30 V absolute maximum rating and that adequate PCB copper area is allocated for heat dissipation given the SO-8 package thermal characteristics.

Part Context

This part belongs to the L78Lxx family of low-power three-terminal positive regulators manufactured by STMicroelectronics. The family offers various fixed output voltages and includes options for through-hole (TO-92) and other surface-mount packages like SOT-89. The L78L series is characterized by its simplicity, requiring minimal external circuitry for stable operation.
