Product details
Overview
MIC2810-4GPYML-TR from Microchip Technology is a digital power management IC integrating a 2 MHz, 600 mA DC/DC buck converter and two independent 300 mA LDOs (LDO1 and LDO2), all with separate enable controls. It delivers fixed output voltages of 1.2 V (DC/DC), 1.8 V (LDO1), and 3.0 V (LDO2), operates from 2.7–5.5 V input, achieves >90% efficiency in PWM mode, and draws only 30 µA total quiescent current in LOWQ mode - ideal for battery-powered embedded MPU systems requiring ultra-low-noise, sequenced power rails.
For engineers reviewing the MIC2810-4GPYML-TR datasheet, MIC2810-4GPYML-TR pinout, MIC2810-4GPYML-TR application, or MIC2810-4GPYML-TR equivalent, this page provides verified technical context, validated pin functions, confirmed low-noise performance in LOWQ mode (53 µVRMS), real-world sequencing behavior via CSET-controlled POR delay, and direct alternative options for dual-LDO + buck PMIC replacement in portable and RF-sensitive designs.
Technical Context
The MIC2810-4GPYML-TR implements a dual-mode regulation architecture: full-power PWM operation (2 MHz, up to 600 mA) for high-efficiency conversion, and LOWQ linear mode (30 µA IQ, 53 µVRMS noise) activated by pulling LOWQ ≤0.2 V. Its three regulated outputs support independent sequencing via EN, EN1, EN2, and programmable POR delay (CSET capacitor sets reset assertion time).
It features separate ground paths (SGND for control circuitry, PGND for high-current switching), integrated thermal shutdown (160°C trip), current limiting (750 mA typical in PWM mode), and leakage-free backup-power interfacing via open-drain POR with ESD-protected clamping-free design - enabling safe use in systems with isolated backup domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Key Features
| Feature | Design Value |
|---|---|
| LOWQ Dual-Mode Operation | Switches between 600 mA PWM (high efficiency) and 60 mA linear (53 µVRMS noise, 30 µA IQ) - eliminates PFM ripple in RF-critical applications. |
| Independent Triple-Output Control | Separate EN, EN1, EN2 pins allow staggered startup/shutdown and flexible power sequencing without external logic. |
| Programmable POR with CSET | CSET pin enables precise, capacitor-set delay (up to 1 s) for coordinated system reset timing across multiple voltage rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar triple-output PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MIC2810-4GSYML-TR | Same package and architecture; LDO2 output is 3.3 V instead of 3.0 V. | Suitable where 3.3 V peripheral rail is required instead of 3.0 V; identical sequencing, noise, and IQ specs. | Select when system requires 3.3 V for USB PHY, SDIO, or legacy I/O - no layout or firmware changes needed. |
| MIC2810-4GMYML-TR | Same package and architecture; LDO2 output is 2.8 V instead of 3.0 V; LDO1 remains 1.8 V. | Optimized for lower-voltage peripherals (e.g., 2.8 V display drivers or memory); same LOWQ performance and POR behavior. | Choose for designs targeting tighter voltage margins or compatibility with 2.8 V interface standards - maintains full functional equivalence. |
Compared with MIC2810-4GPYML-TR, the -4GSYML-TR and -4GMYML-TR variants retain identical pinout, LOWQ operation, POR timing, and thermal protection - differing only in LDO2 output voltage (3.3 V or 2.8 V), making them drop-in replacements where that specific rail voltage aligns with system requirements.

FAQ
What output voltages does the MIC2810-4GPYML-TR provide?
The MIC2810-4GPYML-TR provides three fixed, factory-set output voltages: 1.2 V from the DC/DC converter, 1.8 V from LDO1, and 3.0 V from LDO2. These values are encoded in the part number suffix "4GP" per Microchip's Product Identification System and are not adjustable externally. All outputs support independent enable control and are monitored by the shared POR output.
How does the LOWQ mode affect the MIC2810-4GPYML-TR's output capability and noise performance?
In LOWQ mode (LOWQ pin pulled low), the MIC2810-4GPYML-TR disables its PWM switching regulator and powers the DC/DC output through the LDO pin, delivering up to 60 mA at 1.2 V with 53 µVRMS output noise (10 Hz–100 kHz). Simultaneously, LDO1 and LDO2 remain active but are current-limited to <50 mA each. Total quiescent current drops to 30 µA, making it ideal for ultra-low-power sleep states.
Can the MIC2810-4GPYML-TR be used in systems with backup power domains?
Yes - the MIC2810-4GPYML-TR's POR output is an open-drain N-channel device with no internal clamping diodes to VIN or other supply rails. This allows the POR signal to be safely pulled up to a backup power source (e.g., coin cell or supercapacitor) and asserted to host I/O pins even when main power is removed, enabling robust brownout detection and reset coordination across power domains.
What is the purpose of the CSET pin on the MIC2810-4GPYML-TR, and how is it configured?
The CSET pin on the MIC2810-4GPYML-TR sources a precise 1.25 µA current to charge an external capacitor to ground, setting the POR assertion delay time (in microseconds = capacitance in picofarads). For example, a 100 nF capacitor yields a ~100 ms delay. This enables programmable, glitch-free power sequencing across the three regulated outputs during startup or enable transitions.
Does the MIC2810-4GPYML-TR require external components for stability, and what are the minimum recommendations?
Yes - the MIC2810-4GPYML-TR requires external components for stable operation: a 2.2 µF X5R/X7R ceramic capacitor on each output (DC/DC, LDO1, LDO2); a 4.7 µF X5R/X7R ceramic capacitor on VIN near PGND; a 0.1 µF ceramic capacitor on BIAS to SGND; and an inductor (2.2 µH, rated for ≥600 mA peak current) between SW and the DC/DC output. These values are validated in the datasheet for full-load and transient performance.
