ELECTRICAL CHARACTERISTICS
Boldface limits apply over the specified temperature range, T_A = –40°C to +85°C.
At T_A = +25°C, V_IN = V_OUT/2 + 0.75V, I_OUT = 10mA, C_IN = C_OUT = 2.2µF, C_PUMP = 0.22µF, and V_ENABLE = 1.3V, unless otherwise
noted.

(1) The supply current is twice the output short-circuit current.
(2) The converter regulates by enabling and disabling periods of switching cycles. The switching frequency is the oscillator frequency during
an active period.
(3) See efficiency curves for other V_IN/V_OUT configurations.
(4) Effective series resistance (ESR) of capacitors is < 0.1Ω.
