Product details
Overview
AP2132BMP-1.5TRG1 from Diodes Incorporated is a 2A, 1.5V fixed-output CMOS low-dropout (LDO) regulator in PSOP-8 package with thermal pad, featuring 300mV dropout at 2A, ±2% output voltage accuracy, and integrated power-good (PG) signal asserting at 92% of rated VOUT-designed for core voltage regulation in notebook CPU/GPU power rails.
For engineers reviewing the AP2132BMP-1.5TRG1 datasheet, AP2132BMP-1.5TRG1 pinout, AP2132BMP-1.5TRG1 application, or AP2132BMP-1.5TRG1 equivalent, key selection criteria include dropout performance under 2A load, PG threshold tolerance, enable logic compatibility, thermal resistance (θJA = 53°C/W), and PSOP-8 thermal pad layout requirements.
Technical Context
The AP2132BMP-1.5TRG1 integrates a precision 0.8V reference, error amplifier, PMOS pass transistor, and current-limit/thermal shutdown protection. Its VCTRL pin accepts 4.5–5.5V to bias internal control circuitry independently of VIN, enabling stable operation even when input drops near VOUT.
Power-good assertion occurs when VOUT reaches ≥92% of 1.5V (i.e., ≥1.38V) with 7% hysteresis; the ADJ pin is internally tied to GND for fixed 1.5V output, eliminating external resistors while retaining adjustability if reconfigured.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5V ±2% (1.47V–1.53V) ensures stable core supply for 1.5V I/O domains |
| Max Output Current | 2A continuous-supports high-current SoC subsystems without external boost |
| Dropout Voltage | 300mV @ 2A, 1.5V output-enables operation from 1.8V input rail with margin |
| Input Voltage Range | 1.4V to 5.5V-compatible with single-cell Li-ion (3.0–4.2V) and 3.3V/5V system rails |
| Power-Good Threshold | 92% of VOUT (1.38V) with 7% hysteresis-provides reliable sequencing signal for downstream logic |
| Supply Current | 300µA typical at no load-minimizes quiescent loss in battery-powered standby modes |
| Thermal Resistance | θJA = 53°C/W on 2-layer FR-4 with 1cm² thermal pad-guides PCB copper area design for 2A thermal management |
Pinout & Package
AP2132BMP-1.5TRG1 uses the PSOP-8 package with exposed thermal pad (pin 5 NC, pin 8 GND), requiring solder paste stencil optimization for thermal pad attachment and 0.4mm pitch trace routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (PG) | Power-Good open-drain output | Asserts high when VOUT ≥ 1.38V; requires external pull-up for MCU reset sequencing |
| 2 (EN) | Enable input | Active-high logic: ≥1.2V enables regulator; ≤0.4V disables output and reduces IQ to <1µA |
| 3 (VIN) | Main input supply | Accepts 1.4–5.5V; decoupled with 10µF ceramic capacitor per datasheet layout |
| 4 (VCTRL) | Control voltage input | 4.5–5.5V bias for internal circuitry-decoupled with 1µF capacitor, independent of VIN |
| 5 (NC) | No-connect terminal | Must remain unconnected; not internally bonded-no routing or thermal relief required |
| 6 (VOUT) | Regulated output | 1.5V ±2% source for load; requires 10µF output capacitor with ESR <50mΩ |
| 7 (ADJ) | Output voltage setting | Internally grounded for fixed 1.5V mode; floating or pulled to GND maintains configuration |
| 8 (GND) | Power ground | Common return for VIN, VOUT, VCTRL, EN, PG; connected to thermal pad for heat dissipation |
Key Features
| Feature | Design Value |
|---|---|
| Low dropout at full load | 300mV @ 2A enables use with 1.8V input for 1.5V systems-reducing heat vs. higher-VIN alternatives |
| Integrated power-good signaling | Dedicated PG pin with 92% threshold and 7% hysteresis eliminates need for external supervisor IC |
| VCTRL-biased architecture | Separate 4.5–5.5V VCTRL rail ensures stable internal biasing even during VIN brownout or ripple |
| Overcurrent + thermal protection | Current limit ≥3A and thermal shutdown at +165°C prevent damage during short-circuit or overload events |
| PSOP-8 with thermal pad | Exposed pad lowers θJC to 29°C/W-enabling 2A operation with minimal PCB copper area |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP2132BMP-1.5TRG1 | Fixed 1.5V, PSOP-8, VCTRL bias, PG output | Designed for systems needing sequenced 1.5V with independent control rail | Preferred when VCTRL decoupling simplifies biasing in multi-rail systems |
| Torex XC6210B152MR-G | Fixed 1.5V, SOT-23-5, no VCTRL or PG, 350mV dropout @ 2A | Limited to space-constrained designs without sequencing or bias isolation needs | Select for cost-sensitive, low-pin-count applications where PG and VCTRL are unnecessary |
Compared with XC6210B152MR-G, AP2132BMP-1.5TRG1 provides superior thermal performance (θJA 53 vs. 200°C/W), integrated power-good signaling, and independent VCTRL biasing-making it suitable for thermally demanding, sequenced power architectures where reliability outweighs footprint savings.

FAQ
What is the minimum input voltage required for AP2132BMP-1.5TRG1 to regulate 1.5V output at 2A?
The absolute minimum input voltage is 1.4V, but for reliable 2A regulation at 1.5V output, VIN must exceed VOUT + dropout voltage. With 300mV typical dropout at 2A, VIN ≥ 1.8V is required to maintain regulation across process/voltage/temperature variations per datasheet specifications.
Can the ADJ pin be left floating in the fixed 1.5V version?
Yes-the ADJ pin is internally connected to GND in fixed-output versions like AP2132BMP-1.5TRG1. Leaving it unconnected or tying it to GND maintains 1.5V output; floating poses no risk, but grounding improves noise immunity per Diodes' layout recommendations.
How does the VCTRL pin affect regulator operation if supplied below 4.5V?
VCTRL must be maintained between 4.5V and 5.5V per recommended operating conditions. Below 4.5V, internal bias circuits may malfunction, causing unstable output, erratic PG behavior, or failure to enable-VCTRL is not a logic input but an analog supply rail for internal references and amplifiers.
Is the PSOP-8 thermal pad electrically connected to any internal node?
No-the thermal pad is internally connected only to the die attach paddle and serves solely for heat conduction. It is not electrically tied to GND or any other pin; however, Diodes recommends soldering it to a dedicated GND plane for optimal thermal performance and mechanical stability.
