L7824CD2T-TR

STMicroelectronics · Voltage Regulators - Linear, Low Drop Out (LDO) Regulators · D2PAK

L7824CD2T-TR from STMicroelectronics, in a D2PAK. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 INPUT power_in Unregulated DC input supply pin, labeled INPUT in Figure 3 pin connections (top view) for the D²PAK package; per Table 1 absolute maximum ratings the DC input voltage must not exceed 40 V for this VO=24 V version (35 V for VO=5-18 V versions), and per Table 18 (L7824C) the input is exercised up to VI=38 V.
2 GND power_in Ground/common reference pin, shown as the 'GND' tab in Figure 3 pin connections (top view); this tab is the exposed metal mounting surface used for heat sinking, with thermal resistance junction-to-case of 3 °C/W and junction-to-ambient of 62.5 °C/W for the D²PAK package per Table 2.
3 OUTPUT power_out Regulated output pin, labeled OUTPUT in Figure 3, delivering a fixed 24 V output (23 to 25 V, typ. 24 V at TJ=25 °C, per Table 18 for L7824C) with output current up to 1.5 A per the Features list, internal current limiting, thermal shutdown and SOA protection.
