Product details
Overview
MAX8532EBTJ from Maxim Integrated is a low-noise, low-dropout linear regulator with 2.85V fixed output, delivering up to 200mA from 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, clean voltage rails.
For engineers reviewing the MAX8532EBTJ datasheet, MAX8532EBTJ pinout, MAX8532EBTJ application, or MAX8532EBTJ equivalent, key selection criteria include guaranteed 200mA output, UCSP package footprint constraints, thermal-shutdown behavior at 160°C, and BP pin bypass capacitor requirements for noise suppression.
Technical Context
The MAX8532EBTJ integrates a 1.25V bandgap reference, error amplifier, and internal P-channel MOSFET pass transistor (RDS(ON) ≈ 1Ω) to achieve load-proportional dropout and ultra-low quiescent current independent of load or dropout condition. Its feedback is implemented via an internal resistor divider tied to OUT, eliminating external resistors.
Shutdown is controlled by a logic-level SHDN pin with <1µA off-state current; the BP pin connects to an internal reference node and requires a 10nF ceramic capacitor to form a low-pass filter that reduces output noise to 40µVRMS (10Hz–100kHz). Thermal protection activates at 160°C with 10°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.85V ±3% over -40°C to +85°C - ensures stable core voltage for 2.8V–3.0V logic domains. |
| Max Output Current | 200mA continuous - supports moderate-power RF modules or sensor subsystems without derating. |
| Dropout Voltage | 100mV (typ) at 100mA - enables operation down to VIN = 2.95V while maintaining regulation at full load. |
| Output Noise | 40µVRMS (10Hz–100kHz) with 10nF BP cap - meets low-noise analog supply requirements for ADCs or RF front-ends. |
| PSRR | 62dB at 100Hz - suppresses ripple from noisy DC/DC converters feeding the LDO input. |
| Quiescent Current | 80µA (no load), independent of VIN and VOUT - extends battery life in always-on monitoring circuits. |
| Shutdown Current | 0.01µA (typ) at +25°C - enables deep-sleep modes in portable instrumentation with µA-level system budget. |
Pinout & Package
MAX8532EBTJ 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 designed for fine-pitch PCB assembly using standard reflow profiles (260°C peak for lead-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B2 (IN) | Regulator input supply | Accepts 2.5V–6.5V; requires ≥2.2µF ceramic input capacitor for stability and line transient response. |
| B1 (OUT) | Regulated output | Delivers 2.85V at up to 200mA; requires ≥2.2µF ceramic output capacitor for load transient performance. |
| A1 (GND) | Analog and power ground | Single ground connection; must be low-impedance and routed close to IN/OUT caps to minimize noise coupling. |
| A2 (SHDN) | Logic-controlled shutdown enable | Active-low input; <0.4V = shutdown (<1µA IQ), >1.6V = active; connect directly to MCU GPIO or pull high to IN. |
| A3 (BP) | Reference bypass node | Internal 1.25V reference tap; requires 10nF ceramic capacitor to GND to reduce output noise to 40µVRMS. |
| B3 (N.C.) | No-connect bump | Not electrically connected; must remain unconnected on PCB - no routing or solder mask opening required. |
Key Features
| Feature | Design Value |
|---|---|
| P-channel MOSFET pass element | Eliminates base-drive current loss; enables 80µA IQ across all load conditions including dropout. |
| Integrated current limit | 210mA minimum trip threshold protects against short-circuit faults without external components. |
| Thermal shutdown with hysteresis | 160°C activation / 150°C recovery prevents latch-up during sustained overload or poor heatsinking. |
| Low-noise BP pin architecture | Enables 40µVRMS noise with only a 10nF capacitor - avoids costly multi-stage filtering in space-constrained designs. |
| High PSRR at low frequency | 62dB rejection at 100Hz allows clean 2.85V rail even when powered from switching converter outputs. |

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 |
|---|---|---|---|
| TPS78228DRVT | 2.8V fixed output, 150mA max, 175mV dropout at 100mA, 25µVRMS noise, 1.5mm × 1.5mm DSBGA | Lower noise but reduced current capability; requires different BP-capacitor network (0.47µF) | Select if noise <25µVRMS is critical and load stays ≤150mA; verify PCB land pattern compatibility. |
| MCP1702T-2802E/MB | 2.8V fixed output, 250mA max, 600mV dropout at 100mA, 30µVRMS noise, SOT-23-5 package | Higher dropout limits usable battery range; larger footprint but wider VIN range (2.7V–13.2V) | Select if input voltage may exceed 6.5V or board space allows SOT-23; not suitable for sub-3.0V battery end-of-life. |
Compared with TPS78228DRVT and MCP1702T-2802E/MB, the MAX8532EBTJ uniquely balances 200mA delivery, 100mV dropout, 40µVRMS noise, and 1.16mm × 1.57mm size-making it optimal for space-constrained, battery-critical 2.85V systems where both current and noise matter.

FAQ
What is the output voltage tolerance of the MAX8532EBTJ over temperature and load?
The MAX8532EBTJ guarantees ±3% output voltage accuracy over the full -40°C to +85°C operating temperature range and across 0.1mA to 200mA load current. At +25°C and 1mA load, tolerance tightens to ±1%. This ensures reliable operation for 2.85V logic interfaces without external trimming or calibration.
Can the MAX8532EBTJ operate with input voltages below 2.5V?
No-the MAX8532EBTJ has a specified input voltage range of 2.5V to 6.5V. Below 2.5V, undervoltage lockout (UVLO) engages at 2.25V (typ), disabling regulation. Attempting operation below 2.5V risks unstable output or complete shutdown; it is not rated for sub-2.5V battery chemistries like NiMH or alkaline under depletion.
What capacitor values are required for stable operation of the MAX8532EBTJ?
The MAX8532EBTJ requires a minimum 2.2µF ceramic capacitor on OUT and 2.2µF on IN for full-load stability across temperature. The BP pin requires exactly 10nF (0.01µF) ceramic. For loads <150mA, 1µF on OUT suffices. X7R/X5R dielectrics are recommended; Z5U/Y5V require ≥4.7µF for low-temperature stability.
Does the MAX8532EBTJ support adjustable output voltage?
No-the MAX8532EBTJ is a fixed-output device with 2.85V nominal voltage, as indicated by the "J" suffix in the ordering code. Adjustable variants (e.g., MAX8532ETJ+) exist but require external feedback resistors and are not pin-compatible. The internal feedback divider is trimmed and non-accessible.
How does thermal shutdown behave during continuous overload on the MAX8532EBTJ?
When junction temperature exceeds 160°C, the MAX8532EBTJ disables the pass transistor. After cooling by 10°C (to ~150°C), it automatically resumes regulation. Under sustained overload, this creates pulsed output-useful for fault indication but not for continuous operation. Derate power dissipation per θJA and board layout to avoid cycling.
