MIC5213
Teeny™ SC-70 µCap Low-Dropout Regulator
Final Information
General Description
Features
The MIC5213 is a µCap 80mA linear voltage regulator in the
Teeny™ SC-70 package. Featuring half the footprint of the
standard SOT-23 package, this Teeny™ SC-70 regulator
has very low dropout voltage (typically 20mV at light loads
and 300mV at 80mA) and very low ground current (225µA at
20mA output). It also offers better than 3% initial accuracy
and includes a logic-compatible enable input.
• Teeny™ SC-70 package
• Wide selection of output voltages
• Guaranteed 80mA output
• Low quiescent current
• Low dropout voltage
• Tight load and line regulation
• Low temperature coefficient
• Current and thermal limiting
• Reversed input polarity protection
• Zero off-mode current
The µCap regulator design is optimized to work with low-
value, low-cost ceramic capacitors. The outputs typically
require only 0.47µF of output capacitance for stability.
• Logic-controlled shutdown
• Stability with low ESR ceramic capacitors
Designedespeciallyforhand-held,battery-powereddevices,
theMIC5213canbecontrolledbyaCMOSorTTLcompatible
logicsignal.Whendisabled,powerconsumptiondropsnearly
to zero. If on-off control is not required, the enable pin may be
tied to the input for 3-terminal operation. The ground current
of the MIC5213 increases only slightly in dropout, further
prolongingbatterylife. KeyMIC5213featuresincludecurrent
limiting, overtemperature shutdown, and protection against
reversed battery.
Applications
• Cellular telephones
• Laptop, notebook, and palmtop computers
• Battery-powered equipment
• Bar code scanners
• SMPS post-regulator/dc-to-dc modules
• High-efficiency linear power supplies
The MIC5213 is available in 2.5V, 2.6V, 2.7V, 2.8V, 3.0V,
3.3V, 3.6V, and 5.0V fixed voltages. Other voltages are
available; contact Micrel for details.
