500 mA Low Dropout Voltage Regulators

B4500
Preliminary Information























Pin Connection









Description

The B4500 series are a group of positive output voltage,
three-pin regulators, that provide a high current even
when the input/output voltage differential is small. Very
low power consumption, only 2µA typ., and high
accuracy is achieved though CMOS construction and
programmable fuse technologies. Output voltage: 2.0V
to 6.0V in 0.1V increments.

The B4500 consists of a high-precision voltage
reference, an error correction circuit, and a current
limited output driver.

Available in SOT223 (500mW) and SOT-89 (300mW)
packages minimizing the usage of board real state.
