Preliminary Information
General Description
The MIC5250 is an efficient, precise dual CMOS voltage
regulator optimized for ultra-low-noise applications. The
MIC5250 offers better than 1% initial accuracy, extremely low
dropout voltage (typically 150mV at 150mA) and constant
ground current over load (typically 100µA). The MIC5250
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 MIC5250 provides TTL logic compatible enable
pins. When disabled, power consumption drops nearly to
zero.
The MIC5250 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, push-
pull outputs for faster transient response, and active clamps
to speed up device turnoff. Available in the 10-lead MSOP
(micro-shrink-outline package), the MIC5250 also offers a
range of fixed output voltages.
Features
• Ultralow dropout—100mV @ 100mA
• Ultralow noise—30µV(rms)
• Stability with ceramic, tantalum, or aluminum electrolytic
capacitors
• Load independent, ultralow ground current
• 150mA output current
• Current limiting
• Thermal Shutdown
• Tight load and line regulation
• “Zero” off-mode current
• Fast transient response
• TTL-Logic-controlled enable input
