BD15HC5MEFJ-LBH2

The BD15HC5MEFJ-LBH2 is a high performance linear voltage regulator from Rohm Semiconductor. It is a low-power, low dropout regulator which offers set voltages in a range of 1.5V to 5.0V with a very high accuracy rate of ±0.3%. This voltage regulator is recommended for use in automotive applications such as power management systems and radios. While the device is designed to take up to 30V input, it is also capable of handling a wide range of input voltages, ranging from 3V to 25V. This versatile regulator is available in a variety of package sizes, making it suitable for a range of applications.

The BD15HC5MEFJ-LBH2 has been designed to provide a small, highly efficient solution for voltage regulation. The device features three distinct modes of operation – normal, burst, and sleep – which can be easily selected using the two select pins. The normal mode is enabled when both select pins are connected together and the internal circuitry is enabled. In this mode, the regulator will power the output with a relatively low dropout voltage. The burst mode allows the regulator to reduce power consumption by allowing the output voltage to remain at a minimum level. In this mode, the regulator is activated by an input signal and the output level will be low until the input signal goes high, at which time the output voltage will be restored to its programmed level. Finally, the sleep mode allows the regulator to be completely disabled and it will remain in this mode until it is enabled by an input signal.

In addition to its multiple operating modes, the BD15HC5MEFJ-LBH2 also provides a range of protection features. These include overcurrent protection, thermal tracking, short circuit protection and overvoltage protection. This makes the device suitable for a wide range of applications, including automotive systems. The device is available in packages as small as DIP-8 and SOT-23, making it suitable for use in space constrained designs. Furthermore, the low dropout voltage and high accuracy features of the device make it ideal for use in precision power supply designs.

In conclusion, the BD15HC5MEFJ-LBH2 is a low dropout, high accuracy linear voltage regulator from Rohm Semiconductor. The range of available package sizes, multiple operating modes, and comprehensive protection features make this device suitable for a wide range of automotive, power management systems and radio applications. The low dropout voltage and high accuracy features of the device make it suitable for use in precision power supply designs, and its versatility makes it a great choice for space-constrained designs.
