KIA78L05BP is listed in the Voltage Regulators - Linear, Low Drop Out (LDO) Regulators range at ChipApex. The manufacturer field lists Toshiba Semiconductor and Storage. Its product description is IC REG LINEAR LDO 5V DIP. Review the specifications below when checking this part for your BOM.
The KIA78L05BP is a fixed-output linear voltage regulator IC from Toshiba Semiconductor and Storage. It provides a stable 5V output with a maximum current capacity of 100mA. The device features low dropout characteristics and internal protection mechanisms including thermal shutdown and current limiting. It is housed in a TO-92 package, suitable for surface mount or through-hole applications depending on the specific variant configuration. The regulator operates within a wide input voltage range, ensuring reliable performance in various power supply circuits.
Verify the exact package type (TO-92 vs SOT) and manufacturer origin (Toshiba vs KEC) as part numbers may be shared across foundries. Confirm RoHS compliance status for your specific region requirements. Ensure input voltage does not exceed absolute maximum ratings to prevent damage. Check datasheet for thermal resistance values if operating in high ambient temperatures.
Select this component when a simple, cost-effective 5V regulation is needed for low-current loads under 100mA. Consider thermal dissipation capabilities if the input-output differential is large. Compare against LDO alternatives if lower dropout voltage is critical for battery life. Verify pinout compatibility with existing PCB layouts.
This part belongs to the standard 78xx series of linear regulators, widely used for basic voltage regulation tasks. While originally popularized by National Semiconductor, multiple manufacturers including Toshiba and KEC produce compatible variants. The 'BP' suffix typically indicates a specific package and tape/reel or lead form variation within the manufacturer's catalog.
Direct substitutes include TA78L05F and other 78L05-compatible parts from different vendors. Ensure replacement devices match the 100mA current rating and 5V output. Verify that thermal and electrical characteristics are equivalent for your application environment.
