Low-Noise, Regulated, Negative
Charge-Pump Power Supplies for GaAsFET Bias
ABSOLUTE MAXIMUM RATINGS
Supply Voltage, V IN to GND ..................................-0.3V to 10.5V
V NEGOUT to GND ...................................................-10.5V to 0.3V
V IN to V NEGOUT .........................................................-0.3V to 21V
V OUT t o GND (Note 1) ........................................V NEGOUT to 0.3V
SHDN or OSC (pin 4) Voltage to GND.........-0.3V to (V IN + 0.3V)
Operating Temperature Ranges
MAX85_ISA ......................................................-25°C to +85°C
MAX85_ESA.....................................................-40°C to +85°C
Storage Temperature Range .............................-65°C to +160°C
Lead Temperature (soldering, 10sec) .............................+300°C
Continuous Power Dissipation (T A = +70°C)
SO (derate 5.88mW/°C above +70°C) ........................471mW
Note 1: The output may be shorted to NEGOUT or GND if the package power dissipation is not exceeded. Typical short-circuit
current to GND is 50mA.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(+5V ≤ V IN ≤ +10V, GND = 0V, V OUT = -4.1V, R L = ∞ , T A = T MIN to T MAX , unless otherwise noted. A 100kHz, 50% duty cycle square
wave between GND and V IN is applied to OSC on the MAX852.)

Note 2: The supply voltage can drop to 4.5V, but the output may no longer sink 5mA at -4.1V.
Note 3: The MAX852 will operate with a 50kHz to 250kHz square wave of 40% to 60% duty cycle. For best performance, use an
80kHz to 120kHz square wave with 50% duty cycle.
