General Description
The MIC5247 is an efficient, precise low voltage CMOS
voltage regulator optimized for ultra-low-noise applications.
The MIC5247 offers better than 1% initial accuracy, and 85
μ
A
constant ground current over load (typically 85
μ
A). The
MIC5247 provides a very low noise output, ideal for RF
applications where quiet voltage sources are required. A
noise bypass pin is also available for further reduction of
output noise.
Designed specifically for hand-held and battery-powered
devices, the MIC5247 provides a logic compatible enable pin.
When disabled, power consumption drops nearly to zero.
The MIC5247 also works with low-ESR ceramic capacitors,
reducing the amount of board space necessary for power
applications, critical in hand-held wireless devices.
Key features include current limit, thermal shutdown, a push-
pull output for faster transient response, and an active clamp
to speed up device turnoff. Available in the IttyBitty SOT-23-5
package, the MIC5247 also offers a range of fixed output
voltages.
