Product details
Overview
MAX8532EBTG from Maxim Integrated is a low-noise, low-dropout linear regulator with 3.0V fixed output, delivering up to 200mA from a 2.5V–6.5V input. It features 100mV typical dropout at 100mA, 40µVRMS output noise, and 80µA quiescent current-ideal for battery-powered portable devices requiring stable, quiet voltage regulation.
For engineers reviewing the MAX8532EBTG datasheet, MAX8532EBTG pinout, MAX8532EBTG application, or MAX8532EBTG equivalent, key selection criteria include guaranteed 200mA output, UCSP package footprint constraints, shutdown current <1µA, PSRR of 62dB at 100Hz, and BP-pin–enabled low-noise operation with 0.01µF bypass.
Technical Context
The MAX8532EBTG uses an internal P-channel MOSFET pass transistor (RDS(ON) ≈ 1Ω) enabling load-proportional dropout and eliminating base-drive current loss. Its error amplifier compares a 1.25V bandgap reference against feedback from an internal resistor divider tied to OUT.
Shutdown is controlled via a logic-level SHDN pin that reduces supply current to <1µA; the BP pin connects to an internal RC filter for noise reduction when bypassed with 10nF. Thermal shutdown activates at +160°C with 10°C hysteresis, and current limiting holds output at ≥210mA min under overload.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±3% over -40°C to +85°C and 0.1mA–200mA load |
| Max Output Current | 200mA continuous; current limit starts at 210mA (min), protecting against shorts |
| Dropout Voltage | 100mV (typ) at 100mA - enables operation down to VIN = 3.1V for 3.0V output |
| Output Noise | 40µVRMS (10Hz–100kHz) with 10nF BP capacitor - critical for RF and precision analog stages |
| PSRR | 62dB at 100Hz - suppresses low-frequency supply ripple from switching converters or noisy batteries |
| Quiescent Current | 80µA (no load), independent of VIN and VOUT - extends battery life in always-on subsystems |
| Shutdown Current | 0.01µA (typ) at +25°C - supports ultra-low-power sleep modes in portable systems |
Pinout & Package
The MAX8532EBTG is housed in a 1.16mm × 1.57mm × 0.66mm, 6-bump UCSP (Ultra-Compact Silicon Package) with 3×2 bump grid. The package is RoHS-compliant and requires reflow soldering at +260°C (lead-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B2 (IN) | Regulator input supply | Accepts 2.5V–6.5V; must be decoupled with ≥2.2µF ceramic capacitor |
| B1 (OUT) | Regulated output | Delivers up to 200mA; requires ≥2.2µF output capacitance for stability |
| A1 (GND) | Analog and power ground | Single ground connection; must be low-impedance path to system GND plane |
| A2 (SHDN) | Active-low enable/shutdown control | Pull low (<0.4V) to disable regulator; connect to IN or logic high for operation |
| A3 (BP) | Reference bypass node | Connect 10nF ceramic capacitor to GND to reduce output noise by filtering reference path |
| B3 (N.C.) | No-connect bump | Not internally connected; must remain unconnected on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise regulation | 40µVRMS output noise enabled by dedicated BP pin and external 10nF filter |
| Load-independent quiescent current | 80µA IQ across full load range - ensures predictable battery drain in varying load states |
| Thermal and short-circuit protection | Auto-recovering shutdown at +160°C junction temp; indefinite short-circuit tolerance without damage |
| UCSP footprint efficiency | 1.16mm × 1.57mm area - saves >60% board space vs. SOT-23 while maintaining 200mA capability |
| High PSRR at low frequency | 62dB rejection at 100Hz - effectively isolates sensitive analog circuits from DC-DC converter ripple |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, low-dropout LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS78030DRVR | 3.0V fixed, 150mA max, 250mV dropout at 100mA, 25µVRMS noise, 500nA IQ | Lower output current and higher dropout limit usable headroom; superior noise but lower drive capability | Select when ultra-low IQ (<1µA) and minimal noise dominate over 200mA requirement |
| MCP1700T-3002E/MB | 3.0V fixed, 250mA max, 600mV dropout at 250mA, 30µVRMS noise, 1.6µA IQ | Higher dropout and larger SOT-23-3 package; better current capacity but less efficient at low VIN | Select when board space allows SOT-23 and higher current margin is needed over UCSP size constraint |

FAQ
What is the output voltage tolerance of the MAX8532EBTG over temperature and load?
The MAX8532EBTG provides a fixed 3.0V output with ±3% accuracy across the full operating range of -40°C to +85°C and for load currents from 0.1mA to 200mA. This specification is guaranteed by design and tested in production, ensuring consistent regulation in portable equipment exposed to ambient temperature swings and dynamic load profiles.
Can the MAX8532EBTG operate with input voltages below 2.5V?
No, the MAX8532EBTG has a minimum input voltage of 2.5V per its absolute maximum ratings and electrical characteristics table. Below this, undervoltage lockout engages (VUVLO = 2.25V typ), disabling regulation. Attempting operation below 2.5V risks unstable output or failure to regulate - use only within the specified 2.5V–6.5V input range.
What capacitor values are required for stable operation of the MAX8532EBTG?
The MAX8532EBTG requires a minimum 2.2µF ceramic output capacitor (X7R/X5R dielectric) for stability across temperature and load. Input capacitance should also be ≥2.2µF. For lowest noise, a 10nF ceramic capacitor must be placed between BP and GND. Using smaller or non-ceramic capacitors may cause oscillation or degraded transient response.
Does the MAX8532EBTG support adjustable output voltage?
No, the MAX8532EBTG is a fixed-output device with 3.0V nominal voltage, as indicated by the "G" suffix in its ordering code (per Output Voltage Selector Guide). It does not include external feedback pins or resistor-divider connections - output is set internally and cannot be adjusted. For adjustable variants, refer to the MAX8530/MAX8531 family.
How does thermal shutdown behave during sustained overload in the MAX8532EBTG?
Under sustained overload, the MAX8532EBTG's thermal shutdown activates at +160°C junction temperature, turning off the pass transistor. After cooling by 10°C (to ~+150°C), it automatically resumes regulation - resulting in pulsed output during continuous fault conditions. This auto-recovery protects the device but is not intended for continuous duty; proper heatsinking and power derating are required for steady-state operation.
