MCP1810
Ultra-Low Quiescent Current LDO Regulator
Features Description Ultra-Low Quiescent Current: 20 nA (typical) Ultra-Low Shutdown Supply Current:
1 nA (typical) 150 mA Output Current Capability for VR ≤ 3.5V 100 mA Output Current Capability for VR  3.5V Input Operating Voltage Range: 2.5V to 5.5V Standard Output Voltages (VR): 1.2V, 1.8V, 2.5V,
3.0V, 3.3V, 4.2V Low Dropout Voltage: 380 mV maximum at
150 mA Stable with 1.0 ВµF Ceramic Output Capacitor Overcurrent Protection Space Saving, 8-Lead Very Thin Plastic Dual Flat,
No Lead Package, 2 x 2 mm Body VDFN The MCP1810 is a 150 mA (for VR ≤ 3.5V), 100 mA (for
VR пЂѕ 3.5V) low dropout (LDO) linear regulator that
provides high-current and low-output voltages, while
maintaining an ultra-low 20 nA of quiescent current
during device operation. In addition, the MCP1810 can
be shut down for an even lower 1 nA (typical) supply
current draw. The 150 mA output current capability, combined with
the low output-voltage capability, make the MCP1810 a
good choice for new ultra-long-life LDO applications
that have high-current demands, but require ultra-low
power consumption during sleep states.
The MCP1810 is stable with ceramic output capacitors
that inherently provide lower output noise and reduce
the size and cost of the entire regulator solution. Only
1 ВµF (2.2 ВµF recommended) of output capacitance is
needed to stabilize the LDO. Applications The MCP1810 comes in six standard fixed
output-voltage versions: 1.2V, 1.8V, 2.5V, 3.0V, 3.3V …
