General Description

The MCP1700 is a family of CMOS low dropout (LDO)

voltage regulators that can deliver up to 250 mA of

current while consuming only 1.6 µA of quiescent

current (typical). The input operating range is specified

from 2.3V to 6.0V, making it an ideal choice for two and

three primary cell battery-powered applications, as well

as single cell Li-Ion-powered applications.

The MCP1700 is capable of delivering 250 mA with

only 178 mV of input to output voltage differential

OUT

= 2.8V). The output voltage tolerance of the

MCP1700 is typically ±0.4% at +25°C and ±3%

maximum over the operating junction temperature

range of -40°C to +125°C.

Output voltages available for the MCP1700 range from

1.2V to 5.0V. The LDO output is stable when using only

1 µF output capacitance. Ceramic, tantalum or

aluminum electrolytic capacitors can all be used for

input and output. Overcurrent limit and overtemperature

shutdown provide a robust solution for any application.

Package options include SOT-23, SOT-89, TO-92 and

2x2 DFN-6.

MCP1700 4.0 DETAILED DESCRIPTION 4.1 Output Regulation 4.3 A portion of the LDO output voltage is fed back to the internal error amplifier and compared with the precision internal bandgap reference. The error amplifier output will adjust the amount of current that flows through the P-Channel pass transistor, thus regulating the output voltage to the desired value.

MCP1700 5.0 FUNCTIONAL DESCRIPTION The MCP1700 CMOS low dropout linear regulator is intended for applications that need the lowest current consumption while maintaining output voltage regulation. The operating continuous load of the MCP1700 ranges from 0 mA to 250 mA (VR  2.5V). The input operating voltage ranges from 2.3V to 6.0V, making it capable of operating from two, three or four alkaline cells or a single Li-Ion cell battery input. 5.

The power dissipation resulting from ground current is small enough to be neglected. 6.3.1 POWER DISSIPATION EXAMPLE TJ(RISE) = PTOTAL x RJA TJ(RISE) = 218.

MCP1700 6.4 Voltage Reference The MCP1700 can be used not only as a regulator, but also as a low quiescent current voltage reference. In many microcontroller applications, the initial accuracy of the reference can be calibrated using production test equipment or by using a ratio measurement. When the initial accuracy is calibrated, the thermal stability and line regulation tolerance are the only errors introduced by the MCP1700 LDO.
