6.5 Electrical Characteristics (continued)

Over 0.85 V ≤ VIN ≤ 7 V, VBIAS ≥ VOUT + 1.6 V (VIN ≤ VBIAS ≤ 14 V & VBIAS ≥ 2.2 V), VOUT (target) ≤ VIN – 1.6 V, IOUT = 1 mA,

COUT = 220 µF(1), RREF = 12.0 kΩ, over operating temperature range (TA = –55°C to 125°C), typical values are at TA = 25°C,

unless otherwise noted; includes RLAT at TA = 25°C if sub-group number is present for QML RHA and SEP devices(2)

(1)

A single 220 µF tantalum capacitor is utilized

(2)

See the 5962R21203 SMD for additional information on the QML RHA devices and see the V62/23602 VID for additional information

on the SEP devices.

(3)

The subgroups are only applicable for QML versions of the device; for subgroup definitions, see Section 6.6.

(4)

Additionally, VBIAS ≥ VIN and VBIAS ≥ VOUT + 1.6 V.

(5)

PD is the internal power dissipation. When PD exceeds 4 W, the current is lowered to avoid excessive local heating (due to tester

limitations).

(6)

TID = 100 krad(Si) for QMLV and QMLP parts and TID = 50 krad(Si) for SEP parts.

(7)

See Section 9.3 for additional information.
