Product details
Overview
AP2112M-2.6TRG1 from Diodes Incorporated is a fixed-output 2.6V, 600mA CMOS low-dropout linear regulator with enable control and auto-discharge functionality. It delivers ±1.5% output accuracy, 250mV typical dropout at 600mA, and operates across –40°C to +85°C in SO-8 package. Used for stable local regulation in portable computing and display power rails.
For engineers reviewing the AP2112M-2.6TRG1 datasheet, AP2112M-2.6TRG1 pinout, AP2112M-2.6TRG1 application, or AP2112M-2.6TRG1 equivalent, key selection criteria include guaranteed 600mA load capability, 50µVRMS low-noise output, 65dB PSRR at 100Hz/1kHz, fast 20µs startup time, and thermal shutdown with 160°C trip point.
Technical Context
The AP2112M-2.6TRG1 integrates a precision voltage reference, error amplifier, and PMOS pass transistor in a CMOS architecture enabling ultra-low quiescent current (55µA typ.) and near-zero standby current (0.01µA typ.). Its foldback short-circuit protection limits output current to 50mA under fault conditions.
It features an internal 60Ω discharge path activated when EN is low, ensuring rapid VOUT decay. The regulator remains stable with 1.0µF ceramic, tantalum, or aluminum electrolytic output capacitors and supports input voltages from 2.5V to 6.0V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.6V ±1.5% - ensures tight regulation for 2.6V logic or analog supply domains |
| Max Output Current | 600mA minimum - sustains full-rated load without thermal derating in SO-8 package |
| Dropout Voltage | 250mV typical @ 600mA - enables operation with only 2.85V input for 2.6V output |
| PSRR | –65dB @ 100Hz & 1kHz - suppresses ripple from noisy upstream DC/DC converters |
| Quiescent Current | 55µA typical - minimizes no-load power loss in battery-backed systems |
| Startup Time | 20µs typical - supports fast power sequencing in multi-rail applications |
| Output Noise | 50µVRMS (10Hz–100kHz) - suitable for noise-sensitive analog circuitry |
Pinout & Package
AP2112M-2.6TRG1 is housed in an SO-8 package (RoHS-compliant, lead-free, green). Thermal resistance θJA is 114°C/W (no heatsink), and θJC is 75°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT | Regulated 2.6V output - connects to load and output capacitor |
| 2 | NC | No connection - electrically isolated; must not be tied to any net |
| 3 | VIN | Input supply (2.5–6.0V) - requires local 1.0µF ceramic decoupling |
| 4 | GND | Power ground - shared return for input/output paths and internal circuitry |
| 5 | GND | Power ground - second GND pin improves thermal dissipation and reduces ground impedance |
| 6 | EN | Active-high enable - ≥1.5V enables regulation; ≤0.4V disables output and activates 60Ω discharge |
| 7 | NC | No connection - electrically isolated; must not be tied to any net |
| 8 | NC | No connection - electrically isolated; must not be tied to any net |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-2602E/OT | 250mA max output, SOT23-5 package, higher 350mV dropout at full load | Suitable only for <250mA loads; lacks auto-discharge and dual-GND thermal path | Select when board space is constrained and load current is ≤250mA |
| TLS820B2ELVSE | Automotive-grade AEC-Q100, 300mA, integrated watchdog and reset - no auto-discharge | Designed for automotive body electronics; requires external discharge circuit for VOUT decay | Select only for automotive qualification requirements; not drop-in for consumer/portable use |

FAQ
What is the minimum input voltage required for AP2112M-2.6TRG1 to regulate 2.6V output?
The minimum recommended input voltage is 2.5V per the datasheet's Recommended Operating Conditions. At 600mA load, the typical dropout is 250mV, so VIN ≥ 2.85V ensures regulation margin. Below 2.5V, the device may enter dropout or fail to start, especially under cold-temperature conditions.
Does AP2112M-2.6TRG1 require an external pull-up resistor on the EN pin?
No. The EN pin has an internal 3.0MΩ pull-down resistor, so it defaults to OFF when left floating. A logic-high signal ≥1.5V is required to enable regulation. No external pull-up is needed unless active-low control or specific power-up sequencing demands it.
Can AP2112M-2.6TRG1 be used with a 10µF aluminum electrolytic output capacitor?
Yes. The datasheet explicitly states stability with 1.0µF ceramic, tantalum, or aluminum electrolytic capacitors. A 10µF aluminum electrolytic is acceptable and may improve low-frequency transient response, though ESR should remain within 1Ω–10Ω for optimal loop stability.
How does the auto-discharge function behave during EN deactivation?
When EN is driven low (<0.4V), the internal 60Ω resistor connects VOUT to GND, discharging the output capacitor rapidly. This behavior is confirmed in the Electrical Characteristics table (RDCHG = 60Ω) and Functional Block Diagram, and eliminates need for external discharge circuitry in reset-sensitive systems.
