Infineon BCR116: Low-Dropout Linear Regulator for General Purpose Switching Applications
The Infineon BCR116 is a highly integrated low-dropout (LDO) linear regulator designed to deliver stable and clean voltage in a wide array of general-purpose switching applications. Housed in a compact SOT-23-6 package, this device combines a high-performance NPN regulator with two integrated bias resistors, making it an efficient and space-saving solution for stabilizing voltage levels in circuits where noise and ripple suppression are critical.
A key feature of the BCR116 is its low-dropout voltage, which allows it to continue regulating the output voltage even when the input voltage is only slightly higher than the desired output level. This capability is particularly beneficial in battery-powered devices and other applications where energy efficiency and extended operation are essential. With an output voltage fixed at 5 V and a maximum output current of 70 mA, the BCR116 is well-suited for powering low-power ICs, sensors, and microcontrollers.
The integrated bias resistors simplify circuit design by reducing the external component count, which not only saves board space but also enhances reliability and lowers overall system cost. Furthermore, the device offers excellent load and line regulation, ensuring consistent performance under varying operating conditions. Its ability to suppress noise and ripple from switching power supplies makes it ideal for use in consumer electronics, industrial controls, and automotive systems where clean power is mandatory for sensitive components.

Thermal overload and short-circuit protection mechanisms are also incorporated, safeguarding both the regulator and the downstream circuitry from potential damage due to excessive current or temperature rise. This robustness, combined with Infineon’s manufacturing quality, ensures high reliability in demanding environments.
