Diodes Incorporated AP7342D-2825FS6-7

Overview

AP7342D-2825FS6-7 from Diodes Incorporated is a dual-channel, 150mA low-dropout linear regulator with independent enable control per channel, delivering fixed 2.8V and 2.5V outputs in a 1.2mm × 1.2mm X2-DFN1212-6 package. It features ±1% output voltage accuracy, 75dB PSRR at 1kHz, 60µV_rms output noise (10Hz–100kHz), and 35µA quiescent current per active channel - optimized for RF supply rails and camera sensor power in space-constrained portable electronics.

For engineers reviewing the AP7342D-2825FS6-7 datasheet, AP7342D-2825FS6-7 pinout, AP7342D-2825FS6-7 application, or AP7342D-2825FS6-7 equivalent, key selection criteria include dual independent enable logic, low-noise dual-output capability, thermal performance in ultra-small DFN, and compatibility with 0.47µF ceramic output capacitors without external compensation.

Technical Context

The AP7342D-2825FS6-7 integrates two CMOS-based LDO regulators sharing a common input but operating independently via dedicated EN1 and EN2 pins. Each channel uses a precision voltage reference and error amplifier to maintain regulation across 1.7V–5.25V input range and load currents up to 150mA.

It implements foldback short-circuit protection (≈55mA clamp), auto-discharge functionality on both outputs (enabled by 'D' suffix), and supports stable operation with minimal 0.47µF ceramic output capacitance - eliminating need for ESR tuning or external compensation networks.

Key Specifications

Pinout & Package

The AP7342D-2825FS6-7 is housed in a 1.2mm × 1.2mm, 0.4mm height X2-DFN1212-6 package with exposed thermal pad. PCB layout requires direct connection of the thermal pad to ground plane for optimal thermal dissipation (θ_JA ≈ 220°C/W).

Compared with AP7342D-2825FS6-7, the AP7345D-2825FS6-7 delivers identical performance in a thermally enhanced package with automotive qualification path, while TPL7407LDR forces duplication and sacrifices sequencing flexibility - making the AP7345D the preferred upgrade and the TPL7407LDR a non-optimal fallback.

FAQ

What does the 'D' suffix in AP7342D-2825FS6-7 indicate?

The 'D' suffix denotes integrated auto-discharge functionality on both output channels. When either EN1 or EN2 is pulled low, the corresponding VOUT pin is actively discharged to GND via an internal ~50Ω N-channel FET - preventing residual voltage hold-up that could cause latch-up or leakage in downstream circuits.

Can AP7342D-2825FS6-7 operate with input voltage below 2.5V?

Yes - it supports input voltages as low as 1.7V across its full operating temperature range (−40°C to +85°C). At VIN = 1.7V, the 2.5V output remains functional with ~200mV dropout, while the 2.8V output requires VIN ≥ 2.8V + dropout (≥3.06V typical) to regulate; thus, 2.8V channel will drop out below ~3.1V input.

Is external compensation required for stability?

No - the AP7342D-2825FS6-7 is internally compensated and stable with 0.47µF ceramic output capacitors (X5R/X7R) and ESR as low as 1mΩ. No external RC network or tantalum/bulk capacitor is needed, simplifying layout and reducing bill-of-materials cost.

Why is AP7342D-2825FS6-7 not recommended for new designs?

Diodes Incorporated has designated AP7342 as mature and recommends AP7345D for new designs due to its improved thermal performance (lower θ_JA), extended qualification options (including AEC-Q200), and continued long-term supply commitment - though AP7342D-2825FS6-7 remains fully supported for existing production.
