Product details

Overview

AP2213M-3.0TRE1 from Diodes Incorporated is a fixed 3.0V, 500mA low-noise LDO regulator in SOIC-8 package, featuring 350mV dropout at full load, ±1% output accuracy, 75dB PSRR at 100Hz, and 1µA shutdown current. It delivers stable power to noise-sensitive RF circuitry and portable battery-powered systems where low quiescent current and tight regulation are critical.

For engineers reviewing the AP2213M-3.0TRE1 datasheet, AP2213M-3.0TRE1 pinout, AP2213M-3.0TRE1 application, or AP2213M-3.0TRE1 equivalent, key selection criteria include dropout voltage under 500mA load, PSRR performance at low frequencies, enable logic thresholds, thermal resistance (θ_JA = 160°C/W), and bypass capacitor requirements for noise reduction.

Technical Context

The AP2213M-3.0TRE1 integrates a bandgap reference, error amplifier, and PMOS pass transistor with internal current limiting and thermal shutdown. Its BYP pin connects to a 100pF capacitor to suppress reference noise, directly lowering output noise to 260nV/√Hz.

Enable control is CMOS/TTL-compatible (V_IL ≤ 0.4V, V_IH ≥ 2.0V), supporting low-power system sequencing. Protection includes over-current, over-temperature, and reverse-current blocking-no external diode required.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Voltage	Fixed 3.0V ±1% (ensures stable core/logic rail without external feedback)
Max Output Current	500mA continuous (supports moderate-power microcontrollers and RF ICs)
Dropout Voltage	350mV at 500mA (enables operation from 3.35V input, ideal for single-cell Li-ion or 3.3V bus post-regulation)
PSRR	75dB at 100Hz (rejects switching noise from upstream DC/DC converters)
Standby Current	1µA max in shutdown (extends battery life in always-on sensor nodes)
Output Noise	260nV/√Hz (measured with 100pF BYP capacitor; enables clean supply for VCOs and ADCs)
Thermal Resistance	θ_JA = 160°C/W (SOIC-8, no heatsink; requires derating above +50°C ambient at full load)

Pinout & Package

AP2213M-3.0TRE1 uses the SOIC-8 package (body size 4.9mm × 6.0mm, lead pitch 1.27mm) with matte tin-plated leads, RoHS-compliant and halogen-free ("Green").

Pin/Terminal	Circuit Role	Design Meaning
1	VIN	Main input supply (2.5V–18V); requires ≥1µF ceramic decoupling to GND
2	GND	Power ground reference; pins 5, 6, 7, 8 are internally tied to this node
3	VOUT	Regulated 3.0V output; requires ≥2.2µF ceramic output capacitor when BYP is used
4	EN	Active-high enable; logic high (≥2.0V) activates regulator, low (≤0.4V) disables with 1µA I_STD
5–8	GND	Additional ground terminals; reduce thermal resistance and improve PSRR by lowering ground impedance

Key Features

Feature	Design Value
Low-noise architecture	BYP pin accepts 100pF capacitor to reduce output noise to 260nV/√Hz-critical for RF front-ends and precision analog
Reverse-current protection	Internal MOSFET blocks backflow from VOUT to VIN during shutdown or input collapse-eliminates need for external blocking diode
Tight line/load regulation	Line reg: 4.5mV max (VIN = 4V–13.2V); load reg: 7mV max (I_OUT = 0.1mA–500mA)-maintains voltage stability across dynamic loads
Robust protection suite	Current limit (700–1000mA), thermal shutdown (T_J > +150°C), and ESD rated to 6kV HBM-ensures reliability in industrial and portable environments
High accuracy over temperature	±1% initial accuracy and 40ppm/°C tempco (AP2213-3.0)-guarantees 3.0V ±1.5% across –40°C to +125°C junction range

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MCP1703T-3002E/MB	300mA max output, 600mV dropout at 250mA, no BYP pin, 65dB PSRR at 100Hz	Limited to lower-current logic rails; lacks noise-reduction capability for RF/analog	Choose if cost sensitivity outweighs noise/PSRR requirements and load stays below 300mA
TLS850B2TE/V1	Automotive AEC-Q100 qualified, 500mA, 250mV dropout, integrated watchdog and reset, higher quiescent current (35µA)	Designed for automotive body electronics with functional safety features	Choose only for automotive programs requiring PPAP and ASIL-B support; not drop-in due to different enable behavior and pinout

Compared with MCP1703T-3002E/MB, AP2213M-3.0TRE1 delivers 67% higher current and 10dB better PSRR with dedicated noise suppression. Against TLS850B2TE/V1, it offers 35× lower shutdown current and simpler enable interface-but lacks automotive qualification and system monitoring functions.

FAQ

What is the minimum input voltage required for AP2213M-3.0TRE1 to maintain regulation at 500mA?

The minimum input voltage is 3.35V, calculated as V_OUT + V_DROP = 3.0V + 0.35V. At higher temperatures or loads, dropout may increase up to 700mV per datasheet limits, so 3.7V is recommended for robust operation across –40°C to +125°C junction range.

Can the BYP pin be left unconnected, and what is the impact on performance?

Yes, BYP can be left open. Doing so eliminates the 100pF bypass capacitor, increasing output noise from 260nV/√Hz to ~1.2µV/√Hz but improving startup time and widening the stable ESR range for C_OUT. Use open BYP only when noise is non-critical and fast turn-on is prioritized.

Does AP2213M-3.0TRE1 require an external diode for reverse-voltage protection?

No. The device includes integrated reverse-current protection that blocks conduction from VOUT to VIN when input falls below output voltage-eliminating the need for an external Schottky diode and saving board space and forward-voltage loss.

How does thermal performance differ between SOIC-8 and TO-252-2 (3) packages at 500mA load?

In SOIC-8 (θ_JA = 160°C/W), power dissipation of 0.55W at 500mA causes ~88°C rise above ambient-limiting safe operation to ~+60°C ambient without airflow. TO-252-2 (3) (θ_JA = 90°C/W) reduces rise to ~49°C, enabling full-load operation up to +100°C ambient with minimal heatsinking.
