Key Features
- Ultra-low typical dropout voltage of 0.22 V (maximum 0.5 V) enabling efficient operation close to the supply rail for Li-ion and USB-powered designs
- Adjustable output voltage with tight 0.3%/V line regulation, providing precise and stable rails for analog and mixed-signal circuits
- Lead-free SOIC-8 package with industry-standard footprint, simplifying PCB layout and enabling easy drop-in replacement of comparable LDOs
Applications
The MCP1726-ADJE/SN is ideal for battery-powered portable devices, USB accessories, and handheld instruments where a low dropout voltage is essential to maximize runtime from a depleted battery. Its adjustable output and tight line regulation make it well-suited for powering precision analog front ends, RF modules, and sensor supplies in IoT nodes. The SOIC-8 form factor also fits industrial embedded designs requiring a reliable, cost-effective adjustable LDO in a through-hole-compatible small outline package.

Frequently Asked Questions
What dropout voltage does MCP1726-ADJE/SN achieve, and why does this matter for Li-ion battery designs?
The MCP1726-ADJE/SN has a typical dropout voltage of 0.22 V and a maximum of 0.5 V at rated load. For a Li-ion cell discharging from 4.2 V down to 3.0 V, this low dropout allows the LDO to maintain a regulated 2.8 V output until the cell is nearly fully depleted, maximizing usable battery energy compared to regulators with 1 V or higher dropout.
How do you set the output voltage of MCP1726-ADJE/SN with external resistors?
The MCP1726-ADJE/SN uses an adjustable configuration with an external resistor divider from the output to the ADJ pin. The output voltage is set by selecting two resistors according to the formula Vout = Vref x (1 + R1/R2), where Vref is the internal 1.22 V reference. This allows any output voltage from 1.22 V up to the input voltage minus the 0.22 V nominal dropout to be programmed with standard 1% resistors.
For which precision analog applications is MCP1726-ADJE/SN a good power supply choice?
With a line regulation of 0.3%/V maximum and low noise output, MCP1726-ADJE/SN suits precision ADC reference supplies, op-amp rails, and sensor excitation voltages where a noisy or poorly regulated supply would degrade measurement accuracy. Applications such as 16-bit data acquisition front ends, wheatstone bridge sensor circuits, and precision instrumentation amplifiers benefit from the stable output that this adjustable LDO provides in an SOIC-8 footprint.
