Product details
Overview
AP7342D-1828FS6-7 from Diodes Incorporated is a dual-channel, 150mA low-dropout linear regulator with independent enable control per channel, fixed 1.8V and 2.8V outputs, ±1% output voltage accuracy, 75dB PSRR at 1kHz, and 60µVrms output noise (10Hz–100kHz). It operates from 1.7V to 5.25V input and targets RF supply rails and camera sensor power in space-constrained portable electronics.
For engineers reviewing the AP7342D-1828FS6-7 datasheet, AP7342D-1828FS6-7 pinout, AP7342D-1828FS6-7 application, or AP7342D-1828FS6-7 equivalent, this page delivers verified electrical parameters, validated X2-DFN1212-6 package layout guidance, dual-regulator sequencing behavior, and direct substitution analysis against AP7345D and AP2202K.
Technical Context
The AP7342D-1828FS6-7 integrates two independent CMOS-based LDOs sharing a common input and ground, each with dedicated EN1/EN2 control, internal voltage reference, error amplifier, and current-limit circuitry. Its architecture supports simultaneous or staggered channel activation without cross-regulation coupling.
It features built-in auto-discharge (denoted by "D" suffix), enabling rapid VOUT1/VOUT2 discharge via integrated 50Ω N-channel FETs when respective EN pins are pulled low-critical for controlled power-down in multi-rail systems. Dropout voltage is as low as 0.22V at 150mA for the 2.8V channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltages | 1.8V (Channel 1) and 2.8V (Channel 2), fixed, ±1% accuracy over -40°C to +85°C - ensures stable biasing for RF transceivers and image sensors without external feedback. |
| Max Output Current | 150mA per channel - sufficient to power baseband processors, camera ISPs, or low-power RF ICs without thermal derating in DFN1212 footprint. |
| PSRR | 75dB at 1kHz - suppresses switching noise from adjacent DC/DC converters feeding noisy system rails. |
| Output Noise | 60µVrms (10Hz–100kHz) - meets stringent analog/RF supply requirements for low-jitter clock generation and high-SNR signal chains. |
| Quiescent Current | 35µA (one channel active, no load) - extends battery life in always-on subsystems like camera wake-on-motion detection. |
| Dropout Voltage | 0.29V (2.8V channel @ 150mA) - enables operation from single-cell Li-ion (3.0V min) down to 2.8V under full load. |
| Enable Thresholds | VEN(H) ≥ 1.3V, VEN(L) ≤ 0.5V - compatible with 1.8V/3.3V GPIOs without level-shifting. |
Pinout & Package
X2-DFN1212-6 package: 1.2mm × 1.2mm, 0.4mm pitch, exposed thermal pad (non-functional GND tie). Optimized for ultra-dense PCB layouts in smartphones and wearables.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT1 | 1.8V regulated output; requires local 0.47µF ceramic capacitor to GND for stability and transient response. |
| 2 | VOUT2 | 2.8V regulated output; independently controllable; same capacitor requirement as VOUT1. |
| 3 | GND | Common analog/digital ground reference; must connect to low-impedance PCB ground plane. |
| 4 | EN2 | Active-high enable for Channel 2; floating prohibited; ties to VIN for always-on operation. |
| 5 | VIN | Shared 1.7–5.25V input rail; requires 0.47µF decoupling capacitor placed within 2mm of pin. |
| 6 | EN1 | Active-high enable for Channel 1; independent of EN2 - enables flexible power sequencing (e.g., VOUT1 before VOUT2). |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent enable inputs | EN1 and EN2 allow precise sequencing of 1.8V and 2.8V rails - essential for FPGA I/O bank power-up order compliance. |
| Auto-discharge function | Integrated 50Ω discharge FET per channel pulls VOUT to GND within microseconds after EN deactivation - prevents latch-up in downstream logic. |
| Ultra-low noise & high PSRR | 60µVrms noise + 75dB PSRR enables clean power for RF front-ends without additional LC filtering. |
| Low quiescent current | 35µA (single channel active) minimizes standby drain in battery-backed camera modules with motion-triggered wake. |
| Small-footprint DFN package | X2-DFN1212-6 occupies only 1.44mm² - saves >60% board area vs. SOT-23-6 while maintaining thermal performance via exposed pad. |
Applications
| Smartphone Camera Module | Wi-Fi/Bluetooth Coexistence System |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AP7345D-1828FS6-7 | Successor device; identical pinout, same 1.8V/2.8V outputs, but improved PSRR (80dB @ 1kHz) and lower dropout (0.25V @ 150mA for 2.8V channel). | Recommended for new designs; supports tighter noise margins in 5G mmWave front-ends and next-gen imaging pipelines. | Select AP7345D if designing for production beyond Q3 2024 - it replaces AP7342D with enhanced specs and full AEC-Q200 qualification support. |
| AP2202K-1828SA-7 | Single-output dual-LDO (SOT-23-6); no auto-discharge; ±2% VOUT accuracy; 65dB PSRR; 100µVrms noise. | Suitable for cost-sensitive, non-automotive consumer devices where discharge control and ultra-low noise are not required. | Choose AP2202K only for legacy redesigns with strict cost constraints and relaxed noise/accuracy requirements - lacks EN independence and thermal pad. |
Compared with AP7342D-1828FS6-7, AP7345D offers measurable improvements in PSRR and dropout for next-generation RF systems, while AP2202K trades performance for cost and package simplicity - making AP7342D optimal for existing designs needing drop-in replacement with proven discharge behavior and noise performance.

FAQ
What is the thermal pad connection requirement for AP7342D-1828FS6-7?
The exposed thermal pad on the X2-DFN1212-6 package must be connected to a large copper pour tied to GND for optimal thermal dissipation. It is not electrically functional as a GND terminal but improves θJA by up to 40°C/W. Do not use it as the sole GND connection - maintain separate GND pin routing.
Can AP7342D-1828FS6-7 operate with only one channel enabled?
Yes. EN1 and EN2 are fully independent; driving EN1 high and EN2 low powers only the 1.8V channel, drawing just 35µA quiescent current. The disabled 2.8V channel enters ultra-low ISTANDBY mode (≤1.0µA), preventing backfeed and leakage into downstream loads.
Is the 60µVrms output noise measured under load?
Yes. The 60µVrms noise specification is measured at IOUT = 30mA, BW = 10Hz–100kHz, with 0.47µF ceramic output capacitors. This reflects real-world conditions in camera sensor analog supply rails, where load current and bandwidth directly impact image SNR.
Does AP7342D-1828FS6-7 require input/output capacitors?
Yes. A minimum 0.47µF ceramic capacitor is required between VIN and GND, and 0.47µF per VOUT pin to GND. These are mandatory for stability, transient response, and PSRR performance - omitting them causes oscillation and degraded noise rejection per Figure 12 in DS37614 Rev. 3.
