MIC5206
150 mA Low-Noise LDO Regulator
Features
General Description
• Error Flag Indicates Undervoltage Fault
• High Output Voltage Accuracy
• Ensured 150 mA Output
The MIC5206 is an efficient linear voltage regulator
with very low dropout voltage (typically 17 mV at light
loads and 165 mV at 150 mA), and very low ground
current (600 µA at 100 mA output), with better than 1%
• Ultra Low Noise Output (8-Lead Versions)
• Low Quiescent Current
initial accuracy. It has
a
logic compatible
enable/shutdown control input and an internal
undervoltage monitor.
• Low Dropout Voltage
• Extremely Tight Load and Line Regulation
• Very Low Temperature Coefficient
• Current and Thermal Limiting
• Reversed-Battery Protection
• “Zero” Off-Mode Current
Designed especially for hand-held, battery-powered
devices, the MIC5206 can be switched by a CMOS or
TTL compatible logic signal. When disabled, power
consumption drops nearly to zero. Dropout ground
current is minimized to prolong battery life.
Key features include an undervoltage monitor with an
error flag output, a reference bypass pin to improve its
already low-noise performance (8-lead versions only),
reversed-battery protection, current limiting, and
overtemperature shutdown.
• Logic-Controlled Electronic Enable
Applications
• Cellular Telephones
• Laptop, Notebook, and Palmtop Computers
• Battery-Powered Equipment
The MIC5206 is available in several fixed voltages in a
tiny SOT-23-5 package. It features a pinout similar to
the LP2980, but has significantly better performance.
Fixed and adjustable output voltage versions, featuring
the reference bypass option, are available in the 8-lead
MSOP option.
• PCMCIA VCC and VPP Regulation/Switching
• Consumer/Personal Electronics
• SMPS Post-Regulator/DC-to-DC Modules
• High-Efficiency Linear Power Supplies
For low-dropout regulators that are stable with ceramic
output capacitors, see the µCap MIC5245/6/7 family.
