Description
The B5213 is a µCap, low dropout voltage regulator with very
low quiescent current, 220 µA typical, at 80mA load. It also
has very low dropout voltage, typically 20mV at light load and
330mV at 80mA. The B5213 provides up to 80mA and
consumes a typical of 1 µA in disable mode.
The B5213 is optimized to work with low value, low cost
ceramic capacitors. The output typically require only 0.47 µF
of output capacitance for stability. The enable pin can be tied
to V
IN
for easy device layout.
The B5213 is designed for portable, battery powered
equipment applications with small space requirements.
The B5213 is available in a space saving 5- pin SC70 package.
Performance is specified for the – 40 °C to + 125 °C
temperature range and is available in 2.8V, 3.0V and 3.3V
fixed voltages. For other output voltage options, please contact
