Product details

Overview

AP7315-26W5-7 from Diodes Incorporated is a 2.6V fixed-output, 150mA low-dropout linear regulator with ±1% output voltage accuracy, 75dB PSRR at 1kHz, 60µV_rms output noise (10Hz–100kHz), and 35µA quiescent current - designed for RF supply rails in compact portable electronics.

For engineers reviewing the AP7315-26W5-7 datasheet, AP7315-26W5-7 pinout, AP7315-26W5-7 application, or AP7315-26W5-7 equivalent, this page delivers verified electrical specs, SOT25 package layout guidance, real-world load transient behavior, and validated drop-in alternatives for battery-powered communication subsystems.

Technical Context

The AP7315-26W5-7 employs a CMOS-based LDO architecture with integrated voltage reference, error amplifier, and current-limit protection. Its enable-controlled shutdown reduces standby current to 0.01µA, supporting dynamic power gating in always-on sensor nodes.

It operates across 1.7V–5.25V input range with dropout as low as 210mV at 150mA (for V_OUT = 2.6V), and maintains stability with 0.47µF ceramic output capacitors - eliminating need for external compensation.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 2.6V ±1% - ensures precise biasing of 2.5V–2.7V logic or RF ICs without external feedback network.
Max Output Current	150mA continuous - sufficient for powering single-band RF transceivers or camera ISP cores.
PSRR	75dB at 1kHz - suppresses switching noise from adjacent DC/DC converters feeding shared PCB power planes.
Output Noise	60µV_rms (10Hz–100kHz) - meets low-noise analog supply requirements for ADC references or VCO tuning lines.
Quiescent Current	35µA typical - enables >1-year battery life in BLE/Wi-Fi sleep-mode applications with periodic wake-up bursts.
Dropout Voltage	210mV at 150mA - allows operation down to 2.81V input, compatible with single-cell Li-ion (3.0V–4.2V) or dual-cell alkaline sources.
Enable Threshold	V_EN(H) ≥ 1.3V - compatible with 1.8V/3.3V GPIOs without level-shifting circuitry.

Pinout & Package

SOT25 (5-pin) package with exposed thermal pad; footprint optimized for high-density portable PCBs. Thermal pad must be connected to GND plane for optimal thermal dissipation (θ_JA ≈ 220°C/W on JEDEC High-K board).

Pin/Terminal	Circuit Role	Design Meaning
1 – VIN	Input power supply	Accepts 1.7V–5.25V; requires 0.47µF ceramic capacitor placed within 2mm for stability.
2 – GND	Power ground reference	Must connect directly to low-impedance ground plane; serves as return path for both input and output currents.
3 – EN	Enable control input	Active-high logic; floating state is undefined - tie to VIN if always-on operation is required.
4 – NC	No-connect terminal	Internally unconnected; recommended to tie to GND to maximize copper area for thermal conduction.
5 – VOUT	Regulated output	Delivers stable 2.6V; place 0.47µF ceramic capacitor within 1mm of pin for optimal transient response.

Key Features

Feature	Design Value
High PSRR	75dB @ 1kHz - mitigates ripple from noisy buck converters sharing same battery source.
Ultra-low noise	60µV_rms - avoids phase noise degradation in RF front-end LNAs and mixers.
Low quiescent current	35µA - extends runtime in IoT sensors operating <1% duty cycle.
Wide input range	1.7V–5.25V - supports direct connection to Li-ion, Li-Po, or regulated 3.3V/5V rails.
Thermal shutdown	Integrated protection - disables output above 150°C junction temperature to prevent damage during overload.

Equivalent & Alternatives

The following parts are listed as comparable options for similar LDO regulator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP1700-2602E/TO	2.6V fixed, 250mA, 6µA I_Q, but only 60dB PSRR @ 1kHz and 120µV_rms noise	Lacks RF-grade noise/PSRR performance; suitable for digital-only rails, not analog-sensitive loads	Choose when ultra-low I_Q dominates over noise/PSRR - e.g., coin-cell-powered microcontrollers
Torex XC6206P262MR-G	2.6V fixed, 150mA, 35µA I_Q, 70dB PSRR @ 1kHz, 80µV_rms noise, no enable pin	Missing EN control eliminates dynamic power gating capability; higher noise limits RF/analog use	Choose only if enable functionality is unnecessary and cost is primary constraint in non-critical analog paths

Compared with MCP1700-2602E/TO and XC6206P262MR-G, the AP7315-26W5-7 uniquely balances RF-grade PSRR/noise, enable control, and 150mA drive in a 5-pin SOT25 - making it the sole option among these three for noise-sensitive, dynamically powered RF subsystems.

FAQ

What is the minimum input voltage required for AP7315-26W5-7 to maintain regulation at full 150mA load?

The minimum input voltage is 2.81V - calculated as V_OUT + dropout = 2.6V + 210mV (max dropout at 150mA per datasheet Table 1). Below this, output voltage drops nonlinearly; operation below 1.7V input is prohibited per Absolute Maximum Ratings.

Can the NC pin (Pin 4) in the SOT25 package be left floating?

No - Pin 4 is internally unconnected but must be tied to GND on the PCB. This maximizes copper area under the package for thermal conduction and improves mechanical reliability during reflow, as specified in Diodes' Package Outline Drawing and Application Information section.

Does AP7315-26W5-7 include reverse-current protection?

No - the AP7315-26W5-7 lacks integrated reverse-current blocking. If V_OUT exceeds V_VIN (e.g., during hot-swap or backup battery scenarios), current can flow backward through the pass device. External protection diode or ideal diode controller is required for such use cases.

Is the 60µV_rms output noise specification measured with specific output capacitance?

Yes - the 60µV_rms value is measured with C_OUT = 0.47µF ceramic capacitor, I_OUT = 30mA, and bandwidth 10Hz–100kHz, as defined in Electrical Characteristics Table (Note 9). Using larger or higher-ESR capacitors may increase measured noise due to degraded high-frequency filtering.
