Datasheet - L78 - Positive voltage regulator ICs
TO-220 FPTO-220D PAKDPAKF eatures Output current up to A Output voltages of 5; 6; 8; ; 9; 12; 15; 18; 24 V Thermal overload protection Short circuit protection Output transition SOA protection 2 % output voltage tolerance (A version) Guaranteed in extended temperature range (A version)DescriptionThe L78 series of three-terminal Positive regulators is available in TO-220,TO-220FP, D PAK and DPAK packages and several fixed output voltages, making ituseful in a wide range of regulators can provide local on-card regulation, eliminating the distributionproblems associated with single point regulation. Each type embeds internal currentlimiting, thermal shut-down and safe area protection, making it essentiallyindestructible. If adequate heat sinking is provided, they can deliver over 1 A outputcurrent. Although designed primarily as fixed voltage regulators, these devices canbe used with external components to obtain adjustable voltage and status linkL78 Positive voltage regulator ICsL78 DatasheetDS0422 - Rev 35 - May 2018 For further information contact your local STMicroelectronics sales 2.
Nov 23, 2010 · 1. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account separately. Pulse testing with low duty cycle is used. Note: Minimum load current for regulation is 5 mA. L78 Electrical characteristics DS0422 - Rev 36 page 6/55
