Product details
Overview
AP2114HA-1.2TRG1 from BCD Semiconductor Manufacturing Limited is a fixed-output 1.2 V, 1 A CMOS low-dropout linear regulator with enable control, designed for stable power delivery in noise-sensitive analog and digital subsystems. It delivers ±1.5% output accuracy, 450 mV typical dropout at 1 A (for 3.3 V version; 1.2 V version specifies 1.3 V max dropout), 30 μVRMS output noise, and operates across –40°C to +85°C ambient temperature.
For engineers reviewing the AP2114HA-1.2TRG1 datasheet, AP2114HA-1.2TRG1 pinout, AP2114HA-1.2TRG1 application, or AP2114HA-1.2TRG1 equivalent, key selection criteria include guaranteed 1 A load capability under low-input conditions, thermal shutdown (160°C) and foldback current limiting (50 mA), compatibility with 4.7 μF ceramic output capacitors, and SOT-223 package suitability for space-constrained consumer power rails.
Technical Context
The AP2114HA-1.2TRG1 implements a CMOS-based LDO architecture with internal voltage reference (0.8 V for adjustable variants), precision error amplifier, and PMOS pass transistor-enabling low quiescent current (60 μA) and high PSRR (68 dB @ 1 kHz). Its enable logic (VIH = 1.5 V, VIL = 0.4 V) supports controlled power sequencing in multi-rail systems.
It integrates foldback short-circuit protection, thermal shutdown with 25°C hysteresis, and VOUT discharge via 60 Ω internal resistor when EN is low-critical for safe power-down in LCD bias and STB standby modes. The device is optimized for input voltages from 2.5 V to 6.0 V and requires no external compensation with ≥4.7 μF ceramic output capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.2 V ±1.5% - ensures stable core/bias rail for low-voltage logic and display drivers |
| Max Output Current | 1 A continuous - supports single-chip SoC or multi-channel analog front-end loads |
| Dropout Voltage | 1300 mV max @ 1 A - defines minimum VIN–VOUT margin required for regulation at full load |
| Quiescent Current | 60 μA typical - enables ultra-low-power operation in always-on system blocks |
| Output Noise | 30 μVRMS (10 Hz–100 kHz) - minimizes jitter and ripple-induced errors in ADCs and RF sections |
| PSRR | 68 dB @ 1 kHz - suppresses switching noise from upstream DC/DC converters feeding the LDO input |
| Enable Threshold | VIH = 1.5 V, VIL = 0.4 V - compatible with 1.8 V/3.3 V GPIO without level-shifting |
| Thermal Shutdown | 160°C with 25°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking |
Pinout & Package
AP2114HA-1.2TRG1 uses the SOT-223 (H/HA) package - a thermally enhanced 3-pin surface-mount outline with exposed thermal pad (pin 2 = VIN, pin 3 = VOUT, pin 1 = GND). Pin 2 (VIN) connects to input supply; pin 3 (VOUT) delivers regulated 1.2 V; pin 1 (GND) serves as common return and thermal path.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference and primary thermal conduction path to PCB copper |
| 2 | VIN | Unregulated input supply (2.5–6.0 V); must be decoupled with ≥4.7 μF ceramic capacitor |
| 3 | VOUT | Stable 1.2 V output; requires ≥4.7 μF ceramic output capacitor for stability and transient response |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise regulation | 30 μVRMS output noise enables clean power for precision analog circuits and clock buffers |
| Flexible capacitor support | Stable with 4.7 μF ceramic, tantalum, or aluminum electrolytic - reduces BOM count and board area |
| Integrated enable control | H-level active enable (VIH ≥ 1.5 V) allows precise power sequencing and system-level sleep/wake coordination |
| Foldback current limit | 50 mA short-circuit current - limits power dissipation during fault, easing thermal design |
| VOUT discharge on disable | 60 Ω internal discharge path - ensures rapid VOUT decay to prevent latch-up or back-powering of downstream ICs |
| High PSRR at audio band | 68 dB @ 1 kHz - effectively attenuates ripple from switching regulators operating near 1 MHz fundamental |
Applications
| LCD Monitor Power Rail | LCD TV T-Con Bias Supply |
|---|---|
|
Use Scenario: Supplies 1.2 V bias to timing controller (T-Con) logic and gate driver ICs in 1080p/4K panels. IC Role / Device Role / Timing Role: Primary low-noise post-regulator stepping down from 3.3 V or 5 V DC/DC output to meet tight 1.2 V core voltage tolerance. Use Value: ±1.5% accuracy and 30 μVRMS noise prevent display artifacts (flicker, color shift) caused by supply-induced timing jitter. |
Use Scenario: Powers microcontroller and interface logic in LCD TV main board during standby and active modes. IC Role / Device Role / Timing Role: Enables fast wake-up from deep-sleep (via EN pin) while maintaining <60 μA quiescent current in off-state. Use Value: 60 Ω VOUT discharge ensures T-Con resets cleanly on power-down, eliminating ghost images after channel change. |

|
Use Scenario: Delivers 1.2 V to ARM Cortex-A series SoC cores in STB platforms requiring low EMI and thermal headroom. IC Role / Device Role / Timing Role: Low-dropout operation (1300 mV max) permits use with 2.5 V intermediate bus, minimizing heat generation vs. higher-dropout alternatives. Use Value: 1 A rating supports burst-mode CPU loading without output sag; thermal shutdown (160°C) protects against enclosure overheating. |
Use Scenario: Provides clean 1.2 V to FPGA I/O banks interfacing with HDMI PHY and video DACs. IC Role / Device Role / Timing Role: High PSRR (68 dB @ 1 kHz) rejects noise from adjacent switching power stages, preserving signal integrity on high-speed interfaces. Use Value: Stable regulation over –40°C to +85°C ensures reliable boot and video playback across environmental extremes in home entertainment enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP1700T-1202E/TT | 300 mA max output, 170 mV dropout @ 250 mA, SOT-23 package | Lower current capacity; unsuitable for >500 mA loads or high-temperature derating | Select only for ultra-low-power microcontroller rails where 1 A is unnecessary |
| Torex XC6206P122MR-G | 150 mA max output, 160 mV dropout @ 100 mA, SOT-23-3 | Not rated for 1 A; lacks enable pin and thermal shutdown | Use only in cost-sensitive, low-current sensor nodes-not for STB/LCD power rails |
Compared with MCP1700T-1202E/TT and XC6206P122MR-G, the AP2114HA-1.2TRG1 uniquely combines 1 A output, integrated enable, thermal protection, and low-noise performance in SOT-223-making it the only viable option for thermally demanding, high-current consumer display power applications.

FAQ
What is the minimum input voltage required for AP2114HA-1.2TRG1 to maintain regulation at 1 A?
The absolute minimum input voltage is 2.5 V per recommended operating conditions. At 1 A load, the maximum dropout is 1300 mV, so VIN must be ≥2.5 V to ensure VOUT remains within ±1.5% of 1.2 V across temperature and line variations. Below 2.5 V, regulation fails and output collapses.
Can AP2114HA-1.2TRG1 operate without an output capacitor?
No. The device requires a minimum 4.7 μF ceramic output capacitor for stability, as confirmed in the datasheet's "Stable with 4.7μF Flexible Cap" feature and electrical test conditions. Omitting it causes oscillation, excessive noise, and potential thermal runaway under load.
Is the EN pin internally pulled down?
Yes-the EN pin has a 3.0 MΩ internal pull-down resistor, ensuring the regulator remains disabled (high-impedance VOUT) during power-up or floating control lines. This eliminates need for external pull-down in most designs unless faster turn-on timing is required.
Does AP2114HA-1.2TRG1 support ceramic capacitors with X5R or X7R dielectrics?
Yes. The datasheet explicitly states compatibility with ceramic, tantalum, and aluminum electrolytic capacitors. X5R and X7R MLCCs meet the 4.7 μF minimum requirement and provide optimal ESR for stability-no additional series resistance is needed.
