3 / 9 page Low-Noise 500mA LDO Regulators in a 2mm x 2mm TDFN Package _______________________________________________________________________________________ 3 ELECTRICAL CHARACTERISTICS (continued) (VIN = VEN = 5V, OUTS = OUT, circuit of Figure 2 (MAX8902A) and Figure 3 (MAX8902B), TA = -40°C to +125°C, unless otherwise noted.) (Note 1) PARAMETER CONDITIONS MIN TYP MAX UNITS GND TA < +85°C 80 120 GND Supply Current IOUT = 0mA TA < +125°C 160 µA TA = +25°C 0.001 +1 GND Shutdown Current VIN = 5.5V, EN = 0V TA = +85°C 0.01 µA SELA/SELB (MAX8902A only) When shorted to GND or VIN 500 Ω Select Input Resistance When open 1 M Ω Select Input Capacitance When open 10 pF EN EN rising 0.8 1.2 EN falling, TA < +85°C 0.4 0.7 Enable Input Threshold VIN = 1.7V to 5.5V EN falling, TA < +125°C 0.38 0.7 V TA = +25°C -1 0.001 +1 Enable Input Bias Current VEN = 0V to 5.5V TA = +85°C 0.01 µA POK (MAX8902B only) OUT rising 88 91 94 % POK Threshold OUT voltage when POK switches OUT falling 88 % POK Voltage, Low IPOK = 1mA 10 100 mV TA = +25°C -1 0.001 +1 POK Leakage Current POK = 5.5V, VEN = 0V TA = +85°C 0.01 µA THERMAL SHUTDOWN TJ rising 165 Thermal Shutdown Threshold TJ falling 150 °C OUTPUT TRANSIENT Load Transient IOUT = 50mA to 500mA to 50mA, tRISE = tFALL= 1µs 25 mV/P-P Line Transient VIN = 4V to 5V to 4V, tRISE = tFALL = 5µs, IOUT = 500mA 3 mV/P-P IN-to-OUT Reverse Voltage Turnoff Threshold IN falling below OUT 10 mV Note 1: All devices are production tested at TA = +25°C. Specifications over the operating temperature range are guaranteed by design and characterization. Note 2: The dropout voltage is defined VIN - VOUT, when VOUT is 5% lower than the value of VOUT when VIN = VOUT + 0.5V. |
