MCP1711

150 mA Ultra-Low Quiescent Current, Capacitorless LDO Regulator

Features

General Description

• Low Quiescent Current: 600 nA

• Input Voltage Range: 1.4V to 6.0V

The MCP1711 is a highly accurate CMOS low dropout

(LDO) voltage regulator that can deliver up to 150 mA

of current while consuming only 0.6 µA of quiescent

current (typical). The input operating range is specified

from 1.4V to 6.0V, making it an ideal choice for mobile

applications and one-cell Li-Ion powered applications.

• Standard Output Voltages: 1.2V, 1.8V, 1.9V, 2.2V,

2.5V, 3.0V, 3.3V, 5.0V

• Output Accuracy: ±20 mV for 1.2V and 1.8V

Options and ±1% for V_R> 2.0V

The MCP1711 is capable of delivering 150 mA output

current with only 0.32V (typical) for V_R= 5.0V, and

1.41V (typical) for V_R= 1.2V of input-to-output voltages

differential. The output voltage accuracy of the

MCP1711 is typically ± 0.02V for V_R< 2.0V and ±1% for

V_R> 2.0V at +25°C. The temperature stability is

approximately ±50 ppm/°C. Line regulation is

±0.01%/V typical at +25°C.

• Temperature Stability: ±50 ppm/°C

• Maximum Output Current: 150 mA

• Low ON Resistance: 3.3 @ V_R= 3.0V

• Standby Current: 10 nA

• Protection Circuits: Current Limiter, Short Circuit,

Foldback

• SHDN Pin Function: ON/OFF Logic = Enable

High

The output voltages available for the MCP1711 range

from 1.2V to 5.0V. The LDO output is stable even if an

output capacitor is not connected, due to an excellent

internal phase compensation. However, for better tran-

sient responses, the output capacitor should be added.

The MCP1711 is compatible with low ESR ceramic

output capacitors.

• C_OUTDischarge Circuit when SHDN Function is

Active

• Output Capacitor: Low Equivalent Series

Resistance (ESR) Ceramic, Capacitorless

Compatible

• Operating Temperature: -40°C to +85°C

(Industrial)

Overcurrent limit and short-circuit protection embed-

ded into the device provide a robust solution for any

application.

• Available Packages:

- 4-Lead 1 x 1 mm UQFN

- 5-Lead SOT-23

The MCP1711 has a true current foldback feature.

When the load decreases beyond the MCP1711 load

rating, the output current and output voltage will

foldback toward 80 mA (typical) at approximately 0V

output. When the load impedance increases and

returns to the rated load, the MCP1711 will follow the

same foldback curve as the device comes out of

current foldback.

• Environmentally Friendly: EU RoHS Compliant,

Lead-Free

Applications

• Energy Harvesting

• Long-Life, Battery-Powered Applications

• Portable Electronics

If the device is in Shutdown mode, by inputting a

low-level signal to the SHDN pin, the current

consumption is reduced to less than 0.1 µA (typically

0.01 µA). In Shutdown mode, if the output capacitor is

used, it will be discharged via the internal dedicated

switch and, as a result, the output voltage quickly

returns to 0V.

• Ultra-Low Consumption “Green” Products

• Mobile Devices/Terminals

• Wireless LAN

• Modules (Wireless, Cameras)

Related Literature

The package options for the MCP1711 are the 4-lead

1 x 1 mm UQFN and the 5-lead SOT-23, which make

the device ideal for small and compact applications.
